The _div64 intrinsic divides a 64-bit integer by a 32-bit integer. The return value holds the quotient, and the intrinsic returns the remainder through a pointer parameter. _div64 is Microsoft-specific.

int _div64(
   __int64 dividend,
   int divisor,
   int* remainder
);

dividend
[in] The 64-bit integer to divide.

divisor
[in] The 32-bit integer to divide by.

remainder
[out] The 32-bit integer bits of the remainder.

The 32 bits of the quotient.

The _div64 intrinsic divides dividend by divisor. It stores the remainder in the 32-bit integer pointed to by remainder, and returns the 32 bits of the quotient.

The _div64 intrinsic is available starting in Visual Studio 2019 RTM.
