I don't have any details on the dsPIC hardware, but consider the various
fast division pproaches described in
https://en.wikipedia.org/wiki/Division_algorithm
For the Newton-Raphson method, a better initial guess will reduce the
number of steps

The new dsPIC33CH parts have a 6 cycle divide whereas the older dsPIC33F
takes 18 cycles. The number of cycles is not data dependent.
So I guess more Silicon for fewer cycles, but used how?
