What operations are you doing on the numbers?

I read earlier that Richard reimplemented the division algorithm based
on Knuth's algoithm.  However, the division algorithm in TAOCP Vol 2,
sec 4.3.1 has at least one bug (and I have a $2.56 check ;-).  So, if it
is anything to do with division, I guess Richard should look at which
printing he used to get the algorithm, and also look at the errata
(http://www-cs-faculty.stanford.edu/~knuth/all2.ps.gz) to make sure he
has a correct definition of the algorithm, and a correct implementation.
