### 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.
