Just thought that I would juxtapose two posts to this newsgroup:
Strange as it may seem, the dividers in today's computers can compute
the correct quotient without having the correct remainder around to
return to the user. Fortunately, some can compute the correct remainder
in one operation with a fused multiply add.

Resident arithmetic lunatic
And:
From the Program for the IEEE Symposium on Computer Arithmetic:
8.1 ``Integer Division Using Reciprocals''
Robert Alverson, Tera Computer Company
Nuff said?
(NB. I'm on Bob Alverson's side. This sort of thing is good.)
