SPEAKER 1:

First, let's look at doing division by dividing by quite a small number. Let's do 2,568 divided by 3. This is how it is written. The number you are dividing by goes at the start. That's the 3. And the number you are dividing by 3 goes next that's the 2,568. The first step is to look at the first digit of 2,568, the two, and say how many 3's go into two.

Well, 3's don't go into two. So you should carry the 2 over and say how many 3's go into 25. The answer to that is 8, as 3 times 8 is 24. You show that by writing an eight above the top line above the five. But you've also got one left over as eight times 3 is 24 not 25. So you need to carry over that one. Now you need to ask yourself, how many 3's are there in 16? The answer is 5, as three times 5 is 15.

But again, there is one left over. So you put a 5 above the top line, above the 6 and carry the 1. Next, you need to ask yourself how many 3's are there in 18. The answer is 6 and nothing left over. So put a 6 above the 8 to give 856.

You can also check your answer by working out three times 856. If you get the answer, 2,568, that shows the calculation is correct.
