Programmed Math/Division

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

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:

$$100/4=25$$
