Division and modulo operations are susceptible to divide-by-zero errors.

Division
The result of the / operator is the quotient from the division of the first arithmetic operand by the second arithmetic operand. Division operations are susceptible to divide-by-zero errors. Overflow can also occur during twos-complement signed integer division when the dividend is equal to the minimum (negative) value for the signed integer type and the divisor is equal to -1.

signed long sl1, sl2, result;

/* handle error condition */
}
result = sl1 / sl2;

Modulo
The modulo operator provides the remainder when two operands of integer type are divided.
