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:

$100/4=25$
