How to explain how you got 115 divided by 5?

Answer 1

5 into 1 doesn't go, so take the next digit.

5 into 11 goes twice with 1 left over so put 2 over the second 1 of 11.

You've got 1 left over, so bring the 5 down to join it, and you've got 5 into 15 which is 3 with 0 left over. So put the 3 over the 5 and you see it next to the 2 making 23.

There's no remainder and no more digits in the number being divided, so you're done.

Answer 2

23
