# 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:

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

For an example:

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

And we find that ${\displaystyle 2*50=100}$ So 100 is divisible by 2.

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

So we go onto 4. ${\displaystyle 4*25=100}$ So 100 is divisible by 4.

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

${\displaystyle 100/4=25}$
