There is no way you can do that with doubles. Since the value is too big even for a 64 bit integer, you should use some 128-bit integer class. See for example this[^] or Google for some more.

2+2=5 for very large amounts of 2 (always loved that one hehe!)

The latest .NET 4.0 (and Visual Studio 2010) is in beta and offers a BitInteger class which would easily take care of your big integer division, yielding accurate quotient and remainder values. There also have been some articles on home-brew BigInteger classes here on CP (with varying functionality and quality). :)
