Multiples of a number

I've never used Mod before. I have no clue how it works.

That's what the help files are for.

Basically, this will divide your number as many times as possible by the divisor, then return you the remaining amount.

Ergo:

26/5

1*5=5, 2*5=10, 3*5=15, 4*5=20, 5*5=25, 1 LEFT OVER, so return that.
