PHP Program to find Quotient & Remainder

Let’s write a simple PHP Program to find the Quotient & Remainder. Before writing the program, let’s see a small example of what is a Remainder and a Quotient in mathematics.

Here is an example:
45           ÷         7           =           6           and           3
Dividend Divisor Quotient Remainder

In the above example, 45 is the Dividend, 7 is the Divisor, 6 is the Quotient and 3 is the Remainder.

So the remainder is the “left over” value after dividing one integer by another. Quotient is the quantity produced by the division of 2 integers.

In PHP we can achieve the same with / and %, for eg:
quotion = dividend / divisor -> will give the quotient
remainder = dividend % divisor -> will give the remainder

Let’s write a Simple PHP Script to find the Remainder & Quotient dynamically:

<?php 

if(isset($_POST['submit'])){
	$dividend = $_POST['dividend'];
	$divisor = $_POST['divisor'];
	
	//to find the quotient use /  operator
	$quotient = $dividend / $divisor;
	//to find the remainder use % modules 
	$remainder = $dividend % $divisor;
	
}
?>

					  <button type="submit" name="submit" class="btn btn-primary">Submit</button>
					</form>
				</div>
				<div><strong>Result:</strong><br />
					<!-- Print the result -->
					<?=isset($remainder) ? '<strong>Remainder: </strong>'. $remainder :'';?> 
					<?=isset($quotient) ? '<br><strong>Quotient: </strong>'. round($quotient) :'';?>
				<div>
			</div>
		</div>
	</div>
</body>

Just go through the above code to understand how it works.

You can see the demo of the above PHP script here:
