For most digital designs can you trade between area and speed:

A sequential n-bit divider will use n-clock pulses in order to produces the result (Quotient : Remainder)
On the other hand will a "true parallel" combinatorial division-circuit typically use 3 to 10x times more logic.

The principle of a sequentiel division can be found in textbooks and served as background for the VHDL sources found at this page.
