# How to Divide Two Numbers in Javascript

In this tutorial, you will learn how to divide two numbers in javascript. Division is one of the basic arithmetic operations which every newbie developer should be able to perform without any issue.  But it can also be tricky if you are trying to perform division with 2 values that are coming from 2 different input fields.

Almost in every programming language, we have a division operator (`/`) to divide one number from another and it is also present in javascript. But since the value present in the input field is of string type, we have to convert it into number type using `parseInt()` method and then do the calculation using division operator (`/`).

In the following example, we have 2 input fields in which we will enter 2 random numbers. Upon click of a button, we will perform division and display the result on the screen.  Please have a look over the code example and the steps given below.

HTML & CSS

• We have 4 elements in the HTML file (`div`, `input`, `button`, and `h1`). The `div` element is just a wrapper for the rest of the elements.
• The `innerText` for the `button` element is `“Divide”` and for the `h1` element, it is `“Result”`.
• We have done some basic styling using CSS and added the link to our `style.css` stylesheet inside the `head` element.
• We have also included our javascript file `script.js` with a `script` tag at the bottom.

<input type="number" id="secondInput" placeholder="Enter Denominator">
<button>Divide</button>
<h1>Result</h1>
</div>

<script src="script.js"></script>
</body>
</html>```
```.container {
text-align: center;
}

button {
margin-top: 10px;
}

input {
display: block;
margin: 10px auto;
}

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}```

Javascript

• We have selected both the `input` elements, `button` element, and `h1` element using the `document.querySelector()` method and stored them in `firstInput`, `secondInput`, `btnDivide`, and `output` variables respectively.
• We have attached a `click` event listener to the `button` element.
• In the event handler function, we are passing values of both the `input` elements to the `parseInt()` method and performing calculation using the `division` operator (`/`). The result is stored in the `result` variable.
• We are displaying that `result` in the `h1` element using the `innerText` property.
```let firstInput = document.querySelector('#firstInput');
let secondInput = document.querySelector('#secondInput');
let btnDivide = document.querySelector('button');
let output = document.querySelector('h1');
