<p>Long Division method is used for obtaining the square root for non-perfect squares, mainly. It usually involves the division of the<a>dividend</a>by the<a>divisor</a>, getting a<a>quotient</a>and a<a>remainder</a>for non-perfect squares. To make it simple it is operated on divide, multiply, subtract, bring down and do-again.</p>

<p><strong>Step 5:</strong>Add 1 to the same divisor, 1. We get 2.</p>
8
<p><strong>Step 6:</strong>Now choose a number such that when placed at the end of 2, a 2-digit number will be formed. Multiply that particular number by the resultant number to get a number less than 225. Here, that number is 8. </p>

<p>28×8=224<225. In quotient’s place, we also place that 8.</p>

<p><strong>Step 7:</strong>Subtract 225-224=1. Add a<a>decimal</a>point after the new quotient 18, again, bring down two zeroes and make 1 as 100. Simultaneously add the unit’s place digit of 28, i.e., 8 with 28. We got here, 36. Apply Step 5 again and again until you reach 0. </p>
