David,
I can't help but think this is a sledge hammer to crack a nut solution. I have posted a couple of 32 bit routines that I extracted from an old Intel app note many moons ago that allow you to divide a 32 bit number by a 16 bit one. This wouls allow you to use fixed point arithmetic and reduce your problem immediately to how to convert enough of a 32 bit number to decimal.

A complete solution to your problem in assembler is not too hard. Wait til you get the 8052 ah-basic I am sending to you and try that before you go mad !

I have never needed the FP routines in a real project, so I can't advise you on its use in depth I'm afraid.
