    Use the modulus operator - % and if the result is 0 then it's divisible by 3.

    if( (num % 3)==0 ) /* Num is divisible by 3 */

    The modulus operator (%) returns the remainder of a division. If the remainder is zero then the operand on the left side is divisible by the operand on the right side.
    Code:
    if (number % 3 == 0) {
      /* Divisible by 3 */
    }
