There are various methods to divide an integer number by another number and get its quotient and remainder. 

Example 1: This example uses the Math.floor() function to calculate the divisor. 

HTML




<!DOCTYPE html>
<html>
 
<head>
    <title>
        Integer division with remainder.
    </title>
</head>
 
<body style = "text-align:center;">
    <h1 style = "color:green;" >
        GeeksForGeeks
    </h1>
    <p id = "Geek_up"></p>
    <button onclick = "Geeks()">
        Click Here
    </button>
    <p id = "Geek_down" style = "color:green;"></p>
     
    <script>
        var up = document.getElementById("Geek_up");
        var a = 39;
        var b = 5;
        up.innerHTML = a + "/" + b;
        function Geeks() {
            var down = document.getElementById("Geek_down");
            down.innerHTML = "quotient = " + Math.floor(a/b)
                + "<br>" + "remainder = "+ a%b;
        }
    </script>
</body>
 
</html>

Output:

  • Before clicking on the button:

 

  • After clicking on the button: 

 

Example 2: This example uses the binary ~~ operator to calculate the divisor. 

HTML




<!DOCTYPE html>
<html>
 
<head>
    <title>
        Integer division with remainder.
    </title>
</head>
 
<body style = "text-align:center;">
    <h1 style = "color:green;" >
        GeeksForGeeks
    </h1>
    <p id = "Geek_up"></p>
    <button onclick = "Geeks()">
        Click Here
    </button>
    <p id="Geek_down" style="color:green;"></p>
     
    <script>
        var up = document.getElementById("Geek_up");
        var a = 39;
        var b = 5;
        up.innerHTML = a + "/" + b;
        function Geeks() {
            var down = document.getElementById("Geek_down");
            var num = ~~(a / b);
            down.innerHTML = "quotient = " + num +
                "<br>" + "remainder = "+ a%b;
        }
    </script>
</body>
 
</html>

Output:

  • Before clicking on the button: 

  • After clicking on the button: 

 

Example 3:This example uses the right shift >> operator to calculate the divisor.

    <script>
        var up = document.getElementById("Geek_up");
        var a = 39;
        var b = 5;
        up.innerHTML = a + "/" + b;
        function Geeks() {
            var down = document.getElementById("Geek_down");
            var num = (a / b) >> 0;
            down.innerHTML = "quotient = " + num +
                "<br>" + "remainder = "+ a%b;
        }
    </script>
</body>
