# BigInteger.Division Operator

.NET Framework 4.5

Divides a specified BigInteger value by another specified BigInteger value by using integer division.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

## Syntax

```public static BigInteger operator /(
BigInteger dividend,
BigInteger divisor
)
```

#### Parameters

dividend
Type: System.Numerics.BigInteger

The value to be divided.

divisor
Type: System.Numerics.BigInteger

The value to divide by.

#### Return Value

Type: System.Numerics.BigInteger
The integral result of the division.

## Exceptions

ExceptionCondition
DivideByZeroException

divisor is 0 (zero).

## Remarks

The Division method defines the division operation for BigInteger values. It enables code such as the following:

```BigInteger num1 = 100045632194;
BigInteger num2 = 90329434;
BigInteger quotient = num1 / num2;
```

Languages that do not support custom operators and operator overloading can call the Divide method instead.

## Examples

The following example creates an array of BigInteger values. It then uses each element as the quotient in a division operation that uses the Divide method, the division operator (/), and the DivRem method.

```using System;
using System.Numerics;

public class Example
{
public static void Main()
{
BigInteger divisor = BigInteger.Pow(Int64.MaxValue, 2);

BigInteger[] dividends = { BigInteger.Multiply((BigInteger) Single.MaxValue, 2),
BigInteger.Parse("90612345123875509091827560007100099"),
BigInteger.One,
BigInteger.Multiply(Int32.MaxValue, Int64.MaxValue),
divisor + BigInteger.One };

// Divide each dividend by divisor in three different ways.
foreach (BigInteger dividend in dividends)
{
BigInteger quotient;
BigInteger remainder = 0;

Console.WriteLine("Dividend: {0:N0}", dividend);
Console.WriteLine("Divisor:  {0:N0}", divisor);
Console.WriteLine("Results:");
Console.WriteLine("   Using Divide method:     {0:N0}",
BigInteger.Divide(dividend, divisor));
Console.WriteLine("   Using Division operator: {0:N0}",
dividend / divisor);
quotient = BigInteger.DivRem(dividend, divisor, out remainder);
Console.WriteLine("   Using DivRem method:     {0:N0}, remainder {1:N0}",
quotient, remainder);

Console.WriteLine();
}
}
}
