I was re-reading Hacker's Delight and on page 202 I found a poem about division that I had forgotten about.
I think that I shall never envision
An op unlovely as division.
An op whose answer must be guessed
And then, through multiply, assessed;
An op for which we dearly pay,
In cycles wasted every day.
Division code is often hairy;
Long division's downright scary.
The proofs can overtax your brain,
The ceiling and floor may drive you insane.
Good code to divide takes a Knuthian hero,
But even God can't divide by zero!
Henry S. Warren, author of Hacker's Delight.
