Programmed Math/Division

Division can thought of a reverse multiplication of sorts, where you find how many numbers go into another numnber.

Division is usually in the format:

$\frac{2}{4}$ (two divided by four) OR 2 / 4 = x

For an example:

We want to find out what 100 divides by. We start with 1. We know that 1 * 100 = 100 So 100 is divisible by 1.

And we find that 2 * 50 = 100 So 100 is divisible by 2.

But 3 * 33.33 = 99.99 So 3 isn't. We can't divide 100 by 3 to get a straight answer.

So we go onto 4. 4 * 25 = 100 So 100 is divisible by 4.

And so on for each number. But this format takes too long, so we go:

100 / 4 = 25
