### 2.12 `div`—divide two integers

Synopsis

    #include <stdlib.h>
    div_t div(int n, int d);

Description
Divide n/d, returning quotient and remainder as two integers in a structure `div_t`.

Returns
The result is represented with the structure

     typedef struct
     {
      int quot;
      int rem;
     } div_t;

where the `quot` field represents the quotient, and `rem` the remainder. For nonzero d, if ‘`r = div(n,d);`’ then n equals ‘`r.rem + d*r.quot`’.

To divide `long` rather than `int` values, use the similar function `ldiv`.

Portability
`div` is ANSI.

No supporting OS subroutines are required.
