Dialogue: 0,0:00:00.74,0:00:03.40,Default,,0000,0000,0000,,Let's now see if we can divide into larger numbers.
Dialogue: 0,0:00:03.40,0:00:06.86,Default,,0000,0000,0000,,And just as a starting point, in order to divide into larger numbers,
Dialogue: 0,0:00:06.86,0:00:09.92,Default,,0000,0000,0000,,you at least need to know your multiplication tables
Dialogue: 0,0:00:09.92,0:00:14.55,Default,,0000,0000,0000,,from the one-multiplication tables all the way to, at least, the ten-multiplication.
Dialogue: 0,0:00:14.55,0:00:17.08,Default,,0000,0000,0000,,So all the way up to ten times ten, which you know is one hundred.
Dialogue: 0,0:00:17.08,0:00:20.06,Default,,0000,0000,0000,,And then, starting at one times one and going up to two times three,
Dialogue: 0,0:00:20.06,0:00:22.32,Default,,0000,0000,0000,,all the way up to ten times ten.
Dialogue: 0,0:00:22.32,0:00:23.84,Default,,0000,0000,0000,,And, at least when I was in school,
Dialogue: 0,0:00:23.84,0:00:25.34,Default,,0000,0000,0000,,we learned through twelve times twelve.
Dialogue: 0,0:00:25.34,0:00:28.10,Default,,0000,0000,0000,,But ten times ten will probably do the trick.
Dialogue: 0,0:00:28.10,0:00:29.77,Default,,0000,0000,0000,,And that's really just the starting point.
Dialogue: 0,0:00:29.77,0:00:32.55,Default,,0000,0000,0000,,Because to do multiplication problems like this,
Dialogue: 0,0:00:32.55,0:00:34.15,Default,,0000,0000,0000,,for example, or division problems like this.
Dialogue: 0,0:00:34.15,0:00:39.64,Default,,0000,0000,0000,,Let's say I'm taking twenty-five and I want to divide it by five.
Dialogue: 0,0:00:39.64,0:00:41.12,Default,,0000,0000,0000,,So I could draw twenty-five objects,
Dialogue: 0,0:00:41.12,0:00:44.56,Default,,0000,0000,0000,,and then divide them into groups of five or divide them into five groups,
Dialogue: 0,0:00:44.56,0:00:47.59,Default,,0000,0000,0000,,and see how many elements are in each group.
Dialogue: 0,0:00:47.59,0:00:49.56,Default,,0000,0000,0000,,But the quick way to do is just to think about,
Dialogue: 0,0:00:49.56,0:00:52.93,Default,,0000,0000,0000,,well, five times what is twenty-five, right?
Dialogue: 0,0:00:52.93,0:00:58.10,Default,,0000,0000,0000,,Five times question mark is equal to twenty-five.
Dialogue: 0,0:00:58.10,0:00:59.86,Default,,0000,0000,0000,,And if you know your multiplication tables,
Dialogue: 0,0:00:59.86,0:01:02.07,Default,,0000,0000,0000,,especially your five-multiplication tables,
Dialogue: 0,0:01:02.07,0:01:06.28,Default,,0000,0000,0000,,you know that five times five is equal to twenty-five.
Dialogue: 0,0:01:06.28,0:01:08.83,Default,,0000,0000,0000,,So something like this, you'll immediately just be able to say,
Dialogue: 0,0:01:08.85,0:01:11.69,Default,,0000,0000,0000,,because of your knowledge of multiplication,
Dialogue: 0,0:01:11.69,0:01:14.84,Default,,0000,0000,0000,,that five goes into twenty-five five times.
Dialogue: 0,0:01:14.84,0:01:16.24,Default,,0000,0000,0000,,And you'd write the five right there.
Dialogue: 0,0:01:16.24,0:01:17.18,Default,,0000,0000,0000,,Not over the two,
Dialogue: 0,0:01:17.18,0:01:20.04,Default,,0000,0000,0000,,because you still want to be careful of the place notation.
Dialogue: 0,0:01:20.04,0:01:21.65,Default,,0000,0000,0000,,You want to write the five in the ones place.
Dialogue: 0,0:01:21.65,0:01:25.48,Default,,0000,0000,0000,,It goes into it five ones times, or exactly five times.
Dialogue: 0,0:01:25.48,0:01:26.19,Default,,0000,0000,0000,,And the same thing.
Dialogue: 0,0:01:26.19,0:01:31.77,Default,,0000,0000,0000,,If I said seven goes into forty-nine.
Dialogue: 0,0:01:31.77,0:01:33.25,Default,,0000,0000,0000,,That's how many times?
Dialogue: 0,0:01:33.25,0:01:36.77,Default,,0000,0000,0000,,Well you say, that's like saying seven times what--
Dialogue: 0,0:01:36.77,0:01:39.37,Default,,0000,0000,0000,,you could even, instead of a question mark, you could put a blank there--
Dialogue: 0,0:01:39.39,0:01:43.13,Default,,0000,0000,0000,,seven times what is equal to forty-nine?
Dialogue: 0,0:01:43.13,0:01:45.45,Default,,0000,0000,0000,,And if you know your multiplication tables,
Dialogue: 0,0:01:45.45,0:01:50.09,Default,,0000,0000,0000,,you know that seven times seven is equal to forty-nine.
Dialogue: 0,0:01:50.09,0:01:53.14,Default,,0000,0000,0000,,All the examples I've done so far is a number multiplied by itself.
Dialogue: 0,0:01:53.15,0:01:55.03,Default,,0000,0000,0000,,Let me do another example.
Dialogue: 0,0:01:55.03,0:02:01.84,Default,,0000,0000,0000,,Let me do nine goes into fifty-four how many times?
Dialogue: 0,0:02:01.84,0:02:05.10,Default,,0000,0000,0000,,Once again, you need to know your multiplication tables to do this.
Dialogue: 0,0:02:05.10,0:02:09.29,Default,,0000,0000,0000,,Nine times what is equal to fifty-four?
Dialogue: 0,0:02:09.29,0:02:10.90,Default,,0000,0000,0000,,And sometimes, even if you don't have it memorized,
Dialogue: 0,0:02:10.90,0:02:14.72,Default,,0000,0000,0000,,you could say nine times five is forty-five.
Dialogue: 0,0:02:14.72,0:02:19.47,Default,,0000,0000,0000,,And nine times six would be nine more than that, so that would be fifty-four.
Dialogue: 0,0:02:19.47,0:02:22.38,Default,,0000,0000,0000,,So nine goes into fifty-four six times.
Dialogue: 0,0:02:22.38,0:02:23.59,Default,,0000,0000,0000,,So just as a starting point,
Dialogue: 0,0:02:23.59,0:02:27.25,Default,,0000,0000,0000,,you need to have your multiplication tables from one times one
Dialogue: 0,0:02:27.25,0:02:29.25,Default,,0000,0000,0000,,all the way up the ten times ten memorized.
Dialogue: 0,0:02:29.25,0:02:36.69,Default,,0000,0000,0000,,In order to be able to do at least some of these more basic problems relatively quickly.
Dialogue: 0,0:02:36.70,0:02:38.97,Default,,0000,0000,0000,,Now, with that out of the way, let's try to do some problems
Dialogue: 0,0:02:38.97,0:02:44.02,Default,,0000,0000,0000,,that might not fit completely cleanly into your multiplication tables.
Dialogue: 0,0:02:44.02,0:02:46.19,Default,,0000,0000,0000,,So let's say I want to divide--
Dialogue: 0,0:02:46.19,0:02:54.80,Default,,0000,0000,0000,,I am looking to divide three into forty-three.
Dialogue: 0,0:02:54.80,0:02:58.44,Default,,0000,0000,0000,,And, once again, this is larger than three times ten or three times twelve.
Dialogue: 0,0:02:58.44,0:02:58.93,Default,,0000,0000,0000,,Actually, look.
Dialogue: 0,0:02:58.93,0:03:00.95,Default,,0000,0000,0000,,Well, let me do another problem.
Dialogue: 0,0:03:00.95,0:03:04.26,Default,,0000,0000,0000,,Let me do three into twenty-three.
Dialogue: 0,0:03:04.26,0:03:06.16,Default,,0000,0000,0000,,And, if you know your three-times tables,
Dialogue: 0,0:03:06.16,0:03:10.06,Default,,0000,0000,0000,,you realize that there's three times nothing is exactly twenty-three.
Dialogue: 0,0:03:10.06,0:03:10.91,Default,,0000,0000,0000,,I'll do it right now.
Dialogue: 0,0:03:10.91,0:03:13.28,Default,,0000,0000,0000,,Three times one is three.
Dialogue: 0,0:03:13.28,0:03:15.69,Default,,0000,0000,0000,,Three times two is six.
Dialogue: 0,0:03:15.69,0:03:16.87,Default,,0000,0000,0000,,Let me just write them all out.
Dialogue: 0,0:03:16.87,0:03:24.69,Default,,0000,0000,0000,,Three times three is nine, twelve, fifteen, eighteen, twenty-one, twenty-four, right?
Dialogue: 0,0:03:24.69,0:03:27.70,Default,,0000,0000,0000,,There's no twenty-three in the multiples of three.
Dialogue: 0,0:03:27.70,0:03:29.70,Default,,0000,0000,0000,,So how do you do this division problem?
Dialogue: 0,0:03:29.70,0:03:34.43,Default,,0000,0000,0000,,Well what you do is you think of what is the largest multiple of three that does go into twenty-three?
Dialogue: 0,0:03:34.44,0:03:36.64,Default,,0000,0000,0000,,And that's twenty-one.
Dialogue: 0,0:03:36.64,0:03:39.17,Default,,0000,0000,0000,,And three goes into twenty-one how many times?
Dialogue: 0,0:03:39.17,0:03:44.15,Default,,0000,0000,0000,,Well you know that three times seven is equal to twenty-one.
Dialogue: 0,0:03:44.15,0:03:48.52,Default,,0000,0000,0000,,So you say, well three will go into twenty-three seven times.
Dialogue: 0,0:03:48.52,0:03:50.57,Default,,0000,0000,0000,,But it doesn't go into it cleanly,
Dialogue: 0,0:03:50.57,0:03:53.85,Default,,0000,0000,0000,,because seven times three is twenty-one.
Dialogue: 0,0:03:53.85,0:03:55.75,Default,,0000,0000,0000,,So there's a remainder left over.
Dialogue: 0,0:03:55.75,0:04:00.17,Default,,0000,0000,0000,,So if you take twenty-three minus twenty-one, you have a remainder of two.
Dialogue: 0,0:04:00.17,0:04:08.01,Default,,0000,0000,0000,,So you could write that twenty-three divided by three is equal to seven,
Dialogue: 0,0:04:08.01,0:04:14.100,Default,,0000,0000,0000,,remainder-- maybe I'll just, well, write the whole word out --remainder two.
Dialogue: 0,0:04:15.01,0:04:17.05,Default,,0000,0000,0000,,So it doesn't have to go in completely cleanly.
Dialogue: 0,0:04:17.05,0:04:19.79,Default,,0000,0000,0000,,And, in the future, we'll learn about decimals and fractions.
Dialogue: 0,0:04:19.79,0:04:22.75,Default,,0000,0000,0000,,But for now, you just say, well it goes in cleanly seven times,
Dialogue: 0,0:04:22.75,0:04:24.29,Default,,0000,0000,0000,,but that only gets us to twenty-one.
Dialogue: 0,0:04:24.29,0:04:26.11,Default,,0000,0000,0000,,But then there's two left over.
Dialogue: 0,0:04:26.11,0:04:28.51,Default,,0000,0000,0000,,So you can even work with the division problems
Dialogue: 0,0:04:28.51,0:04:31.08,Default,,0000,0000,0000,,where it's not exactly a multiple of the number
Dialogue: 0,0:04:31.08,0:04:33.31,Default,,0000,0000,0000,,that you're dividing into the larger number.
Dialogue: 0,0:04:33.31,0:04:37.72,Default,,0000,0000,0000,,But let's do some practice with even larger numbers.
Dialogue: 0,0:04:37.72,0:04:40.52,Default,,0000,0000,0000,,And I think you'll see a pattern here.
Dialogue: 0,0:04:40.52,0:04:47.06,Default,,0000,0000,0000,,So let's do four going into--
Dialogue: 0,0:04:47.06,0:04:51.80,Default,,0000,0000,0000,,I'm going to pick a pretty large number here --three hundred forty-four.
Dialogue: 0,0:04:51.80,0:04:53.69,Default,,0000,0000,0000,,And, immediately when you see that,
Dialogue: 0,0:04:53.69,0:04:57.85,Default,,0000,0000,0000,,you might say, hey Sal, I know up to four times ten or four times twelve.
Dialogue: 0,0:04:57.85,0:04:59.85,Default,,0000,0000,0000,,Four times twelve is forty-eight.
Dialogue: 0,0:04:59.85,0:05:01.34,Default,,0000,0000,0000,,This is a much larger number.
Dialogue: 0,0:05:01.34,0:05:02.77,Default,,0000,0000,0000,,This is way out of bounds
Dialogue: 0,0:05:02.77,0:05:05.42,Default,,0000,0000,0000,,of what I know in my four-multiplication tables.
Dialogue: 0,0:05:05.42,0:05:08.38,Default,,0000,0000,0000,,And what I'm going to show you right now is a way of doing this,
Dialogue: 0,0:05:08.38,0:05:10.91,Default,,0000,0000,0000,,just knowing your four-multiplication tables.
Dialogue: 0,0:05:10.91,0:05:11.89,Default,,0000,0000,0000,,So what you do is you say
Dialogue: 0,0:05:11.89,0:05:16.80,Default,,0000,0000,0000,,four goes into this three how many times?
Dialogue: 0,0:05:16.80,0:05:17.48,Default,,0000,0000,0000,,And you're actually saying
Dialogue: 0,0:05:17.48,0:05:20.43,Default,,0000,0000,0000,,four goes into this three how many hundred times?
Dialogue: 0,0:05:20.43,0:05:22.59,Default,,0000,0000,0000,,So this is-- because this is three hundred, right?
Dialogue: 0,0:05:22.59,0:05:24.88,Default,,0000,0000,0000,,This is three hundred forty-four.
Dialogue: 0,0:05:24.88,0:05:29.93,Default,,0000,0000,0000,,But four goes into three no hundred times, or four goes into--
Dialogue: 0,0:05:29.95,0:05:32.81,Default,,0000,0000,0000,,I guess the best way to think of it --four goes three zero times.
Dialogue: 0,0:05:32.81,0:05:34.47,Default,,0000,0000,0000,,So you can just move on.
Dialogue: 0,0:05:34.47,0:05:36.26,Default,,0000,0000,0000,,Four goes into thirty-four.
Dialogue: 0,0:05:36.26,0:05:41.46,Default,,0000,0000,0000,,So now we're going to focus on the thirty-four.
Dialogue: 0,0:05:41.46,0:05:43.90,Default,,0000,0000,0000,,So four goes into thirty-four how many times?
Dialogue: 0,0:05:43.90,0:05:46.90,Default,,0000,0000,0000,,And here we can use our four-multiplication tables.
Dialogue: 0,0:05:46.90,0:05:51.95,Default,,0000,0000,0000,,Four-- Let's see, four times eight is equal to thirty-two.
Dialogue: 0,0:05:51.95,0:05:56.21,Default,,0000,0000,0000,,Four times nine is equal to thirty-six.
Dialogue: 0,0:05:56.21,0:05:59.63,Default,,0000,0000,0000,,So four goes into thirty-four-- nine is too many times, right?
Dialogue: 0,0:05:59.63,0:06:01.50,Default,,0000,0000,0000,,Thirty-six is larger than thirty-four.
Dialogue: 0,0:06:01.50,0:06:03.75,Default,,0000,0000,0000,,So four goes into thirty-four eight times.
Dialogue: 0,0:06:03.75,0:06:06.09,Default,,0000,0000,0000,,There's going to be a little bit left over.
Dialogue: 0,0:06:06.09,0:06:09.03,Default,,0000,0000,0000,,Four goes into thirty-four eight times.
Dialogue: 0,0:06:09.03,0:06:10.86,Default,,0000,0000,0000,,So let's figure out what's left over.
Dialogue: 0,0:06:10.86,0:06:11.56,Default,,0000,0000,0000,,And really we're saying,
Dialogue: 0,0:06:11.56,0:06:14.95,Default,,0000,0000,0000,,four goes into three hundred forty how many ten times?
Dialogue: 0,0:06:14.95,0:06:17.81,Default,,0000,0000,0000,,So we're actually saying four goes into three hundred forty eighty times.
Dialogue: 0,0:06:17.81,0:06:20.02,Default,,0000,0000,0000,,Because notice we wrote this eight in the tens place.
Dialogue: 0,0:06:20.02,0:06:22.88,Default,,0000,0000,0000,,But just for our ability to do this problem quickly,
Dialogue: 0,0:06:22.88,0:06:24.95,Default,,0000,0000,0000,,you just say four goes into thirty-four eight times,
Dialogue: 0,0:06:24.95,0:06:28.77,Default,,0000,0000,0000,,but make sure you write the eight in the tens place right there.
Dialogue: 0,0:06:28.77,0:06:30.10,Default,,0000,0000,0000,,Eight times four.
Dialogue: 0,0:06:30.10,0:06:30.97,Default,,0000,0000,0000,,We already know what that is.
Dialogue: 0,0:06:30.97,0:06:34.14,Default,,0000,0000,0000,,Eight times four is thirty-two.
Dialogue: 0,0:06:34.14,0:06:36.29,Default,,0000,0000,0000,,And then we figure out the remainder.
Dialogue: 0,0:06:36.29,0:06:38.16,Default,,0000,0000,0000,,Thirty-four minus thirty-two.
Dialogue: 0,0:06:38.16,0:06:40.40,Default,,0000,0000,0000,,Well, four minus two is two.
Dialogue: 0,0:06:40.40,0:06:42.03,Default,,0000,0000,0000,,And then these threes cancel out.
Dialogue: 0,0:06:42.03,0:06:43.30,Default,,0000,0000,0000,,So you're just left with a two.
Dialogue: 0,0:06:43.30,0:06:46.12,Default,,0000,0000,0000,,But notice we're in the tens column, right?
Dialogue: 0,0:06:46.12,0:06:48.71,Default,,0000,0000,0000,,This whole column right here, that's the tens column.
Dialogue: 0,0:06:48.71,0:06:55.12,Default,,0000,0000,0000,,So really what we said is four goes into three hundred forty eighty times.
Dialogue: 0,0:06:55.12,0:06:58.35,Default,,0000,0000,0000,,Eighty times four is three hundred twenty, right?

Dialogue: 0,0:07:00.84,0:07:05.70,Default,,0000,0000,0000,,And then, there is--
Dialogue: 0,0:07:05.70,0:07:07.22,Default,,0000,0000,0000,,let me clean this up a little bit.
Dialogue: 0,0:07:07.22,0:07:08.87,Default,,0000,0000,0000,,I didn't want to make that line there look like a--
Dialogue: 0,0:07:08.87,0:07:10.51,Default,,0000,0000,0000,,when I was dividing the columns-- to look like a one.
Dialogue: 0,0:07:10.51,0:07:11.93,Default,,0000,0000,0000,,But then there's a remainder of two,
Dialogue: 0,0:07:11.93,0:07:14.27,Default,,0000,0000,0000,,but I wrote the two in the tens place.
Dialogue: 0,0:07:14.27,0:07:15.74,Default,,0000,0000,0000,,So it's actually a remainder of twenty.
Dialogue: 0,0:07:15.74,0:07:16.99,Default,,0000,0000,0000,,But let me bring down this four.
Dialogue: 0,0:07:16.99,0:07:18.66,Default,,0000,0000,0000,,Because I didn't want to just divide into three hundred forty.

Dialogue: 0,0:07:20.29,0:07:22.29,Default,,0000,0000,0000,,So you bring down the four.
Dialogue: 0,0:07:22.29,0:07:24.44,Default,,0000,0000,0000,,Let me switch colors.
Dialogue: 0,0:07:24.44,0:07:26.67,Default,,0000,0000,0000,,And then-- So another way to think about it.
Dialogue: 0,0:07:26.67,0:07:31.25,Default,,0000,0000,0000,,We just said that four goes into three hundred forty-four eighty times, right?
Dialogue: 0,0:07:31.25,0:07:33.05,Default,,0000,0000,0000,,We wrote the eight in the tens place.
Dialogue: 0,0:07:33.05,0:07:35.55,Default,,0000,0000,0000,,And then eight times four is three hundred twenty.
Dialogue: 0,0:07:35.55,0:07:38.17,Default,,0000,0000,0000,,The remainder is now twenty-four.
Dialogue: 0,0:07:38.17,0:07:40.80,Default,,0000,0000,0000,,So how many times does four go into twenty-four?
Dialogue: 0,0:07:40.80,0:07:41.63,Default,,0000,0000,0000,,Well we know that.
Dialogue: 0,0:07:41.63,0:07:46.16,Default,,0000,0000,0000,,Four times six is equal to twenty-four.
Dialogue: 0,0:07:46.16,0:07:49.11,Default,,0000,0000,0000,,So four goes into twenty-four six times.
Dialogue: 0,0:07:49.11,0:07:50.68,Default,,0000,0000,0000,,And we put that in the ones place.
Dialogue: 0,0:07:50.68,0:07:53.48,Default,,0000,0000,0000,,Six times four is twenty-four.
Dialogue: 0,0:07:53.48,0:07:54.56,Default,,0000,0000,0000,,And then we subtract.
Dialogue: 0,0:07:54.56,0:07:56.27,Default,,0000,0000,0000,,Twenty-four minus twenty-four.
Dialogue: 0,0:07:56.27,0:07:58.49,Default,,0000,0000,0000,,That's-- We subtract at that stage, either case.
Dialogue: 0,0:07:58.49,0:07:59.53,Default,,0000,0000,0000,,And we get zero.
Dialogue: 0,0:07:59.53,0:08:01.05,Default,,0000,0000,0000,,So there's no remainder.
Dialogue: 0,0:08:01.05,0:08:05.85,Default,,0000,0000,0000,,So four goes into three hundred forty-four exactly eighty-six times.
Dialogue: 0,0:08:05.85,0:08:09.18,Default,,0000,0000,0000,,So if your took three hundred forty-four objects and divided them into groups of four,
Dialogue: 0,0:08:09.18,0:08:10.90,Default,,0000,0000,0000,,you would get eighty-six groups.
Dialogue: 0,0:08:10.90,0:08:12.95,Default,,0000,0000,0000,,Or if you divided them into groups of eighty-six,
Dialogue: 0,0:08:12.95,0:08:13.88,Default,,0000,0000,0000,,you would get four groups.
Dialogue: 0,0:08:13.88,0:08:15.64,Default,,0000,0000,0000,,Let's do a couple more problems.
Dialogue: 0,0:08:15.64,0:08:18.44,Default,,0000,0000,0000,,I think you're getting the hang of it.
Dialogue: 0,0:08:18.44,0:08:21.18,Default,,0000,0000,0000,,Let me do seven-- I'll do a simple one.
Dialogue: 0,0:08:21.18,0:08:24.79,Default,,0000,0000,0000,,Seven goes into ninety-one.
Dialogue: 0,0:08:24.79,0:08:28.39,Default,,0000,0000,0000,,So once again, well, this is beyond seven times twelve,
Dialogue: 0,0:08:28.39,0:08:31.34,Default,,0000,0000,0000,,which is eighty-four, which you know from our multiplication tables.
Dialogue: 0,0:08:31.34,0:08:34.65,Default,,0000,0000,0000,,So we use the same system we did in the last problem.
Dialogue: 0,0:08:34.65,0:08:37.75,Default,,0000,0000,0000,,Seven goes into nine how many times?
Dialogue: 0,0:08:37.75,0:08:41.22,Default,,0000,0000,0000,,Seven goes into nine one time.
Dialogue: 0,0:08:41.22,0:08:44.64,Default,,0000,0000,0000,,One times seven is seven.
Dialogue: 0,0:08:44.64,0:08:48.33,Default,,0000,0000,0000,,And you have nine minus seven is two.
Dialogue: 0,0:08:48.33,0:08:51.19,Default,,0000,0000,0000,,And then you bring down the one.
Dialogue: 0,0:08:51.19,0:08:51.77,Default,,0000,0000,0000,,Twenty-one.
Dialogue: 0,0:08:51.77,0:08:53.04,Default,,0000,0000,0000,,And remember, this might seem like magic,
Dialogue: 0,0:08:53.04,0:08:57.54,Default,,0000,0000,0000,,but what we really said was seven goes into ninety ten\Ntimes--
Dialogue: 0,0:08:57.54,0:08:59.96,Default,,0000,0000,0000,,ten because we wrote the one in the tens place--
Dialogue: 0,0:08:59.96,0:09:02.47,Default,,0000,0000,0000,,ten times seven is seventy.
Dialogue: 0,0:09:02.47,0:09:05.05,Default,,0000,0000,0000,,Right?-- You could almost put a zero there if you like--
Dialogue: 0,0:09:05.05,0:09:08.38,Default,,0000,0000,0000,,And ninety-one minus seventy is twenty-one.
Dialogue: 0,0:09:08.38,0:09:12.64,Default,,0000,0000,0000,,So seven goes into ninety-one ten times remainder twenty-one.
Dialogue: 0,0:09:12.64,0:09:15.78,Default,,0000,0000,0000,,And then you say seven goes into twenty-one-- Well you know that.
Dialogue: 0,0:09:15.78,0:09:17.59,Default,,0000,0000,0000,,Seven times three is twenty-one.
Dialogue: 0,0:09:17.59,0:09:20.17,Default,,0000,0000,0000,,So seven goes into twenty-one three times.
Dialogue: 0,0:09:20.17,0:09:22.71,Default,,0000,0000,0000,,Three times seven is twenty-one.
Dialogue: 0,0:09:22.71,0:09:24.55,Default,,0000,0000,0000,,You subtract these from each other.
Dialogue: 0,0:09:24.55,0:09:26.38,Default,,0000,0000,0000,,Remainder zero.
Dialogue: 0,0:09:26.38,0:09:31.91,Default,,0000,0000,0000,,So ninety-one divided by seven is equal to thirteen.
Dialogue: 0,0:09:31.91,0:09:32.53,Default,,0000,0000,0000,,Let's do another one.
Dialogue: 0,0:09:32.53,0:09:35.86,Default,,0000,0000,0000,,And I won't take that little break to explain the places and all of that.
Dialogue: 0,0:09:35.86,0:09:36.80,Default,,0000,0000,0000,,I think you understand that.
Dialogue: 0,0:09:36.80,0:09:41.57,Default,,0000,0000,0000,,I want, at least, you to get the process down really really well in this video.
Dialogue: 0,0:09:41.58,0:09:44.99,Default,,0000,0000,0000,,So let's do seven-- I keep using the number seven.
Dialogue: 0,0:09:44.99,0:09:46.51,Default,,0000,0000,0000,,Let me do a different number.
Dialogue: 0,0:09:46.51,0:09:56.56,Default,,0000,0000,0000,,Let me do eight goes into six hundred eight how many times?

Dialogue: 0,0:10:05.36,0:10:06.82,Default,,0000,0000,0000,,Let me write down the eight.

Dialogue: 0,0:10:09.11,0:10:11.34,Default,,0000,0000,0000,,Let me scroll down a little bit.
Dialogue: 0,0:10:11.34,0:10:13.76,Default,,0000,0000,0000,,I need some space above the number.
Dialogue: 0,0:10:13.76,0:10:15.58,Default,,0000,0000,0000,,So eight goes into sixty how many times?
Dialogue: 0,0:10:15.58,0:10:19.59,Default,,0000,0000,0000,,We know that eight times seven is equal to fifty-six.
Dialogue: 0,0:10:19.59,0:10:23.33,Default,,0000,0000,0000,,And that eight times eight is equal to sixty-four.
Dialogue: 0,0:10:23.33,0:10:25.64,Default,,0000,0000,0000,,So eight goes into-- sixty-four is too big.
Dialogue: 0,0:10:25.64,0:10:26.77,Default,,0000,0000,0000,,So it's not this one.
Dialogue: 0,0:10:26.77,0:10:29.88,Default,,0000,0000,0000,,So eight goes into sixty, seven times.
Dialogue: 0,0:10:29.88,0:10:31.74,Default,,0000,0000,0000,,There's going to be a little bit left over.
Dialogue: 0,0:10:31.74,0:10:34.60,Default,,0000,0000,0000,,So eight goes into sixty, seven times.
Dialogue: 0,0:10:34.60,0:10:35.73,Default,,0000,0000,0000,,Since we're doing the whole sixty,
Dialogue: 0,0:10:35.73,0:10:38.80,Default,,0000,0000,0000,,we put the seven above the ones place in the sixty,
Dialogue: 0,0:10:38.80,0:10:41.06,Default,,0000,0000,0000,,which is the tens place in the whole thing.

Dialogue: 0,0:10:48.99,0:10:50.27,Default,,0000,0000,0000,,Or if we wanted, we can borrow.
Dialogue: 0,0:10:50.27,0:10:51.51,Default,,0000,0000,0000,,That be a ten.
Dialogue: 0,0:10:51.51,0:10:53.38,Default,,0000,0000,0000,,That would be a five.
Dialogue: 0,0:10:53.38,0:10:54.89,Default,,0000,0000,0000,,Ten minus six is four.
Dialogue: 0,0:10:54.89,0:10:59.93,Default,,0000,0000,0000,,Then you bring down this eight.
