Best way to divide in bash using pipes?

Question

I\'m just looking for an easy way to divide a number (or provide other math functions). Let\'s say I have the following command:

find . -name \'*.mp4\' | wc -l
<

Depending on your bash version, you don't even need find for this simple task:

shopt -s nullglob globstar
files=( **/*.mp4 )
dc -e "3 k ${#files[@]} 3 / p"

This method will correctly handle the bizarre edgecase of filenames containing newlines.
