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?

I don't have any details on the dsPIC hardware, but consider the various  
fast division pproaches described in

For the Newton-Raphson method, a better initial guess will reduce the  
number of steps
