# BigInteger.DivRem(BigInteger, BigInteger, BigInteger) Method

## Definition

Divides one BigInteger value by another, returns the result, and returns the remainder in an output parameter.

``````public:
static System::Numerics::BigInteger DivRem(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor, [Runtime::InteropServices::Out] System::Numerics::BigInteger % remainder);``````
``public static System.Numerics.BigInteger DivRem (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor, out System.Numerics.BigInteger remainder);``
``static member DivRem : System.Numerics.BigInteger * System.Numerics.BigInteger * BigInteger -> System.Numerics.BigInteger``
``Public Shared Function DivRem (dividend As BigInteger, divisor As BigInteger, ByRef remainder As BigInteger) As BigInteger``

#### Parameters

dividend
BigInteger

The value to be divided.

divisor
BigInteger

The value to divide by.

remainder
BigInteger

When this method returns, contains a BigInteger value that represents the remainder from the division. This parameter is passed uninitialized.

#### Returns

BigInteger

The quotient of the division.

#### Exceptions

`divisor` is 0 (zero).

## 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();

## Remarks

This method preserves both the quotient and the remainder that results from integer division. If you are not interested in the remainder, use the Divide method or the division operator; if you are only interested in the remainder, use the Remainder method.

The sign of the returned `remainder` value is the same as the sign of the `dividend` parameter.

The behavior of the DivRem method is identical to that of the Math.DivRem method.
