CSharp - Write program to Integer Division and Remainder


33 divided by 7 can either 4.71428 or 4 with remainder 5. It is called Integer Division.

You will do integer division differently from normal division.


In C#, you use the same operator, the slash (/), for both types.

If you put a slash between two values of the int type, the slash performs integer division.

If at least one of the two values is of double type, the slash performs normal division.

You will do normal and integer divisions of the two numbers entered by the user.

To compute the remainder, you use the % operator (percent sign).

You have the following two ways to force the entered values to doubles to achieve "normal" division.

  • Assignment to variables of type double.
  • Type cast to double.

        Console.Write("Enter 1. whole number (dividend): ");
        string input1 = Console.ReadLine();
        int number1 = Convert.ToInt32(input1);

        Console.Write("Enter 2. whole number (divisor): ");
        string input2 = Console.ReadLine();
        int number2 = Convert.ToInt32(input2);

        // Integer calculations 
        int integerQuotient = number1 / number2;
        int remainder = number1 % number2;

        // Alternatively 
        double normalQuotientAlternatively = (double)number1 / (double)number2;

        // Outputs 
        Console.WriteLine("Integer quotient: " + integerQuotient + " with remainder " + remainder);
        Console.WriteLine("\"Normal\" quotient : " + normalQuotient);
        Console.WriteLine("\"Normal\" quotient (alternatively): " + normalQuotientAlternatively);
