/ Operator (C# Reference)

The division operator (/) divides its first operand by its second operand. All numeric types have predefined division operators.

User-defined types can overload the / operator (see operator). An overload of the / operator implicitly overloads the /= operator.

When you divide two integers, the result is always an integer. For example, the result of 7 / 3 is 2. To determine the remainder of 7 / 3, use the remainder operator (%). To obtain a quotient as a rational number or fraction, give the dividend or divisor type float or type double. You can assign the type implicitly if you express the dividend or divisor as a decimal by putting a digit to the right side of the decimal point, as the following example shows.

class Division
{
    static void Main()
    {        
        Console.WriteLine("\nDividing 7 by 3.");
        // Integer quotient is 2, remainder is 1.
        Console.WriteLine("Integer quotient:           {0}", 7 / 3);
        Console.WriteLine("Negative integer quotient:  {0}", -7 / 3);
        Console.WriteLine("Remainder:                  {0}", 7 % 3);
        // Force a floating point quotient. 
        float dividend = 7;
        Console.WriteLine("Floating point quotient:    {0}", dividend / 3);

        Console.WriteLine("\nDividing 8 by 5.");
        // Integer quotient is 1, remainder is 3.
        Console.WriteLine("Integer quotient:           {0}", 8 / 5);
        Console.WriteLine("Negative integer quotient:  {0}", 8 / -5);
        Console.WriteLine("Remainder:                  {0}", 8 % 5);
        // Force a floating point quotient.
        Console.WriteLine("Floating point quotient:    {0}", 8 / 5.0);
    }
}
// Output: 
//Dividing 7 by 3. 
//Integer quotient:           2 
//Negative integer quotient:  -2 
//Remainder:                  1 
//Floating point quotient:    2.33333333333333 

//Dividing 8 by 5. 
//Integer quotient:           1 
//Negative integer quotient:  -1 
//Remainder:                  3 
//Floating point quotient:    1.6
