Divides one BigInteger value by another and returns the result.
public:
static System::Numerics::BigInteger Divide(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor);
public static System.Numerics.BigInteger Divide (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor);
static member Divide : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Function Divide (dividend As BigInteger, divisor As BigInteger) As BigInteger
Parameters
- dividend
- BigInteger
The value to be divided.
- divisor
- BigInteger
The value to divide by.
Returns
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.One,
BigInteger.Multiply(Int32.MaxValue, Int64.MaxValue),
divisor + BigInteger.One };
// Divide each dividend by divisor in three different ways.

BigInteger quotient;
BigInteger remainder = 0;
Console.WriteLine("Dividend: {0:N0}", dividend);

Console.WriteLine("Results:");
Console.WriteLine(" Using Divide method: {0:N0}",
BigInteger.Divide(dividend, divisor));
Console.WriteLine(" Using Division operator: {0:N0}",

Console.WriteLine();

Remarks
The Divide method performs integer division; any remainder that results from the division is discarded. To perform integer division while preserving the remainder, call the DivRem method. To retrieve only the remainder, call the Remainder method.
The Divide method can be used by languages that do not support operator overloading. Its behavior is identical to division using the division operator.
