Most useful piece of code !

Very useful for adapting 8051 to tasks probably better suited to a 16-32 bitter !

Useful in limited contexts.

These functions certainly work well, but application is obviously limited by the small range of divisors. Excellent for radix conversion.

Works great.

Hi. I've just use that code and it works brilliant. it made me save a lot of time trying to implement it myself. It's ideal for divisions by 10.
