What do you mean - not supported by ARM? Of course ARM supports 64
bit division.
Compiling this little test code:
long long div(long long x, long long y)
{
return x / y;
}
will result in a call to __aeabi_ldivmod using an EABI compliant
version of GCC, resp. to __divdi3 using an older compiler. So GCC
knows how to handle this, and it provides adequate functions to do
it.

I really hesitate to do that. It seems that not using the compiler
provided library is not such a clever thing to do. The compile writes
probably know better what a specific version of GCC needs that
anybody else.
Best regards,
