_cairo_uint_96by64_32x64_divrem:

Compute a 32 bit quotient and 64 bit remainder of a 96 bit unsigned dividend and 64 bit divisor. If the quotient doesn't fit into 32 bits then the returned remainder is equal to the divisor, and the quotient is the largest representable 64 bit integer. It is an error to call this function with the high 32 bits of ‘num’ being non-zero.
