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!...
