2 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 2005, we need to group it as 05 and 20.</p>

3 <p><strong>Step 2:</strong>Now we need to find n whose square is closest to 20. We can say n is 4 because 4 x 4 = 16, which is lesser than or equal to 20. Now the<a>quotient</a>is 4, and the<a>remainder</a>is 20 - 16 = 4.</p>

5 <p><strong>Step 4:</strong>We need to find the largest possible digit x such that 8x * x ≤ 405. For x = 5, 85 * 5 = 425, which is more than 405. For x = 4, 84 * 4 = 336, which is<a>less than</a>405.</p>

6 <p><strong>Step 5:</strong>Subtract 336 from 405; the remainder is 69. Our quotient is now 44.</p>
6 <p><strong>Step 5:</strong>Subtract 336 from 405; the remainder is 69. Our quotient is now 44.</p>
7 <p><strong>Step 6:</strong>Since the dividend is less than the divisor, we need to add a decimal point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 6900.</p>

9 <p><strong>Step 8:</strong>Subtracting 6209 from 6900 gives us a remainder of 691.</p>
