It is only part of the frameRate counter.

Reference:

> Calculates the remainder when one number is divided by another. For example, when 52.1 is divided by 10, the divisor (10) goes into the dividend (52.1) five times (5 \* 10 == 50), and there is a remain…

Lots of uses for modulo:  
[Make modulo your friend!](https://community.tableau.com/message/686694#686694) Concepts can be adapted for Processing.
