SPEAKER 1:
To divide 23.6 by 5, you would first ask yourself, how many 5s in two? As 5 doesn't go into two, you would carry the two, and ask yourself, how many 5s in 23? Since 4 times 5 is 20 the answer is 4 with 3 left over that need to be carried. So now you need to add the 4 above the top line above the 3. Here you can also see the 3 has carried over to be with the 6 after the decimal point. Even though this is after the decimal point, the carrying just works like before.
At this point, before you do anything else you need to put a decimal point on the top line exactly above the one under the line. Now, you should ask yourself, how many 5s in 36? The answer is 7 as 7 times 5 is 35, with 1 left over that you'll need to carry. So put the 7 on the top line after the decimal point.
You may now be thinking, how am I going to carry the 1 as there aren't any more digits left? The way to do this is to put an extra 0 after the 6. This is OK to do is 23.6 is the same number as 23.60. The 0 just means there is zero hundredths. Now, ask yourself, how many fives in 10? The answer to that is 2, and nothing left over. So you'd put the 2 above the 0, and you have finished. The answer to 23.6 divided by 5 is 4.72.
