title: Integral operators quot vs. div
body: <p>Type class Integral has two operations <code>quot</code> and <code>div</code>, yet in the Haskell 2010 Language Report it is not specified what they're supposed to do. Assuming that <code>div</code> is integral division, what does <code>quot</code> differently, or what is the purpose of <code>quot</code>? When do you use one, and when the other?</p>
