20 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 65, we need to group it as 65.</p>
22 <p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 65. We can say n as ‘8’ because 8 x 8 = 64, which is less than 65. Now the<a>quotient</a>is 8, and after subtracting 64 from 65, the<a>remainder</a>is 1.</p>

22 <p><strong>Step 3:</strong>Since the remainder is less than the<a>divisor</a>and we need more precision, we add a<a>decimal</a>point and bring down two zeros to make the new dividend 100.</p>
24 <p><strong>Step 4:</strong>Double the quotient (8), making it 16, and find a number x such that 16x x ≤ 100. We find x as 0, so 160 x 0 = 0.</p>
23 <p><strong>Step 4:</strong>Double the quotient (8), making it 16, and find a number x such that 16x x ≤ 100. We find x as 0, so 160 x 0 = 0.</p>
25 <p><strong>Step 5:</strong>Subtracting 0 from 100 gives us a remainder of 100.</p>
24 <p><strong>Step 5:</strong>Subtracting 0 from 100 gives us a remainder of 100.</p>
26 <p><strong>Step 6:</strong>Bring down another set of zeros, making the new dividend 10000. Now, find x such that 1600x x ≤ 10000. We find x as 6, because 1606 x 6 = 9636.</p>
