Well, that's more a feature of the compiler.  Perhaps you want to
replace the “long” by `64-bit' to be more exact?  (Though AVR-GCC's
64-bit support, while working, is not its brightest side, arguably.)

The 64-bit integer support has been improved with the avr-gcc 4.7
release series, see the 4.7 release notes


For technical details cf.


This leads to the paradoxical situation that for specific
values the 64-bit division routine works faster than the
32-bit division routine for these values.
