lldiv_t lldiv(long long int numer, long long int denom);

**lldiv** computes **numer** / **denom** and **numer** % **denom**
in a single operation.

**lldiv** returns a structure of type lldiv_t
comprising both the quotient and the remainder. The structures contain the members
**quot** (the quotient) and **rem** (the remainder), each of which has
the same type as the arguments **numer** and **denom**. If either part
of the result cannot be represented, the behavior is undefined.
