I never thought about that. But here's one way you could do it, that might even

be related to some of the math you're doing in school just now:

- - Take the number that has to be divided.

- - Find all of its factors.

- - If you divide it by one of its factors, then there will be no remainder.

- - If you divide it by any other number, then there will be a remainder.

Some numbers just don't fit into other numbers perfectly. 3 does not go into 7 perfectly. It goes into 6 perfectly, but not 7.

When you get division problems such as 7 divided by 3, expect to deal with remainders. Just by looking at those two numbers, you can see that there is something wrong. 3 goes into 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, etc, etc. It just isn't in harmony with 7 ...

It's important to learn your times tables so that you can automatically distinguish numbers that are in harmony and those that aren't.
