LPM_DIVIDER [More than 64 bits necessary]

Greetings, Simple background/story: Here I am implementing a pipelined version of double-precision floating point arithmetics with the format: So far I've managed to implement addition, ...

Why not directly use one of the iterative algorithms (for example see http://en.wikipedia.org/wiki/division_algorithm), taking the initial estimate from a direct array lookup of the first few mantissa bits.

If you can guarantee a fixed number of iterations, then you can pipeline it isnstead.

The early iterations can probably drop some of the least significant bits.
