Paul pointed you to this URL, more specifically,

http://www.emesys.com/BS2math6.htm#multiplication

shows how to do double precision (32 bit product) and quad precision (64 bit product) multiplication. Double precision muliplication is easy thanks to the ** operator.

Then,

http://www.emesys.com/BS2math6.htm#showdubdec

shows how to display the number as decimal digits for DEBUG or for other display. There are also routines there for double precision addition, subtraction, etc.
