Just for verification: So Python can't store the value 1/3 as .3 repeating like a calculator can? So if I set a variable equal to 1/3 it won't actually be equal to .3 repeating? Seems quite unreasonable to me.

Function modulo is easy.
For example 14 modulo 3. We must find number, which is smaller than 14 (<14), can be divided ( /) and it will be rational number (1, 2, 3... Not numbers like 3,123). It's 12 (12/3=4). Then we just subtract 14 and 12 (14-12). It's 2.
