gmp_divexact — Exact division of numbers
   Divides num1 by num2,
   using fast "exact division" algorithm. This function produces
   correct results only when it is known in advance that
   num2 divides num1.
  
num1The number being divided.
 A GMP object, an int,
 or a string that can be interpreted as a number following the same logic
 as if the string was used in gmp_init() with automatic
 base detection (i.e. when base is equal to 0).
num2
       The number that num1 is being divided by.

A GMP object.
Example #1 gmp_divexact() example
<?php
$div1 = gmp_divexact("10", "2");
echo gmp_strval($div1) . "\n";
$div2 = gmp_divexact("10", "3"); // bogus result
echo gmp_strval($div2) . "\n";
?>The above example will output:
5 2863311534
