# Find quotient and remainder by dividing an integer in JavaScript

Dividing an integer is a mathematical operation where we divide a number into two parts, the quotient, and the remainder. In JavaScript, we use this operation to perform various calculations and to get the desired result. In this article, we will discuss how to find the quotient and remainder by dividing an integer in JavaScript.

### Algorithm

The algorithm for dividing an integer in JavaScript is straightforward. We divide the number into two parts, the quotient, and the remainder. The quotient is the result of the division, and the remainder is the part of the number that is left over after the division.

## Approach 1

In this approach, we use the Math.floor() function to find the quotient and the modulo operator (%) to find the remainder. The Math.floor() function returns the largest integer that is less than or equal to the given number. In this case, it returns the quotient. The modulo operator returns the remainder after dividing the number by the divisor.

var quotient = Math.floor(number/divisor);
var remainder = number % divisor;


### Example 1

var number = 14;
var divisor = 3;
var quotient = Math.floor(number/divisor);
var remainder = number % divisor;
console.log("Quotient: " + quotient);
console.log("Remainder: " + remainder);


## Approach 2

In this approach, we use the parseInt() function to find the quotient and subtraction to find the remainder. The parseInt() function returns an integer by removing the decimal part of the number. In this case, it returns the quotient. To find the remainder, we subtract the product of the quotient and divisor from the number.

var quotient = parseInt(number/divisor);
var remainder = number - quotient * divisor;


### Example 2

var number = 14;
var divisor = 3;
var quotient = parseInt(number/divisor);
var remainder = number - quotient * divisor;
console.log("Quotient: " + quotient);
console.log("Remainder: " + remainder);


## Conclusion

In this article, we discussed how to find the quotient and remainder by dividing an integer in JavaScript. We looked at two different approaches, one using the Math.floor() function and the modulo operator and the other using the parseInt() function and subtraction. We also provided two working examples to show how the code can be used in real-world applications. By following these approaches, you can easily find the quotient and remainder in JavaScript.
