java.math.BigInteger divide(BigInteger val)


On this document we will be showing a java example on how to use the divide(BigInteger val) method of BigInteger Class. Basically this method returns a BigInteger whose value is (this / val). Since the result would be BigInteger and wouldn’t be able to hold fractions, then the remainder would be discarded. If you are interested on the remainder better use the divideAndRemainder(BigInteger val) method of BigInteger class.


  • this method throws an ArithmeticException when the val method argument supplied is zero.

Method Syntax

public BigInteger divide(BigInteger val)

Method Argument

Data Type Parameter Description
BigInteger val value by which this BigInteger is to be divided.

Method Returns

The divide() method returns this / val.


Requires Java 1.1 and up

Java BigInteger divide() Example

Below is a java code demonstrates the use of divide() method of BigInteger class. The example presented might be simple however it shows the behavior of the divide() method.


import java.math.BigInteger;
import java.util.Scanner;

 * A java example source code to demonstrate
 * the use of divide() method of BigInteger class

public class BigIntegerDivideExample {

	public static void main(String[] args) {	
		// ask for user input
		System.out.print("Enter the dividend:");
		Scanner s = new Scanner(;
		String dividend = s.nextLine();
		System.out.print("Enter the divisor:");
		String divisor = s.nextLine();
		// convert the string input to BigInteger
		BigInteger val1 = new BigInteger(dividend);
		BigInteger val2 = new BigInteger(divisor);
		// get the quotient
		BigInteger result = val1.divide(val2);
		System.out.println("Result of the operation is:"+result);		


This example is a lot simpler than it looks. We simply ask the user for two inputs, the first one is the dividend and the other is divisor. The quotient were derived in using the divide() method of the BigInteger class.

Sample Output

Below is the sample output when you run the above example.
