Is the modulus operator (%) useful?

I observe a lot of new programmers, and I've noticed that they tend to avoid the modulus operator (%), even after they learn about it.

This video provides a few useful scenarios when you might want to start using it in your programs, specifically when trying to determine even division and manage circular buffers.

The examples are in C, but the use of the operator applies easily to C++, java, python, ruby, and most other imperative languages.
