There is an efficient integer division method by any constant described in the
R. Alverson. Integer Division Using Reciprocals. In 10th Symposium on Computer
Arithmetic, pages 186--190, 1991.
Most of the computation is done at compile time (generation of constants used
by the algorithm). At run-time, you would have about 5-6 instrns. The
algorithm is fairly simple to implement
