/ Operator (C# Reference) 

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

Remarks

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

Example

// cs_operator_division.cs
using System;
class MainClass
{
    static void Main() 
    {
        Console.WriteLine(-5/2);
        Console.WriteLine(-5.0/2);
    }
}

Output

-2
-2.5
