Ah, that's what he's after. No, I don't think there is a way of using the
DIV instruction in the 8051 to speed up a multi-byte divide.

Good thought, though. It *is* possible to use the MUL instruction to speed
up multi-byte  multipication (do partial products and add).

Yes, the DIV instruction is of little use, perhaps in addressing of data
structures in memory, but MUL is usually what I end up using.

Best regards,
