Many people I know and work with simplify the modulo operator to 
themselves as remainder, so mentally (whether or not it is correct) 
assume 0/7 = 0 r 7
I am just making an explicit example of this not necessarily obvious 
case.  It's totally fine when one knows the semantics of modulo, it's 
the simplification to remainder that many people make that causes 
problems here.
