20 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 312, we group it as 12 and 3.</p>
19 <p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 312, we group it as 12 and 3.</p>
21 <p><strong>Step 2:</strong>Now we need to find n whose square is 3. We can say n is '1' because 1^2 is lesser than or equal to 3. Now the<a>quotient</a>is 1; after subtracting 1 from 3, the<a>remainder</a>is 2.</p>

22 <p><strong>Step 3:</strong>Now let us bring down 12, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number: 1 + 1 = 2, which will be our new divisor.</p>
21 <p><strong>Step 3:</strong>Now let us bring down 12, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number: 1 + 1 = 2, which will be our new divisor.</p>
23 <p><strong>Step 4:</strong>The new divisor will be the<a>sum</a>of the dividend and quotient. Now we get 2n as the new divisor; we need to find the value of n.</p>
22 <p><strong>Step 4:</strong>The new divisor will be the<a>sum</a>of the dividend and quotient. Now we get 2n as the new divisor; we need to find the value of n.</p>
24 <p><strong>Step 5:</strong>The next step is finding 2n × n ≤ 212. Let us consider n as 8, now 28 x 8 = 224.</p>
23 <p><strong>Step 5:</strong>The next step is finding 2n × n ≤ 212. Let us consider n as 8, now 28 x 8 = 224.</p>
25 <p><strong>Step 6:</strong>Subtract 212 from 224; the difference is -12, and the quotient is 18.</p>
24 <p><strong>Step 6:</strong>Subtract 212 from 224; the difference is -12, and the quotient is 18.</p>
26 <p><strong>Step 7:</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 1200.</p>
25 <p><strong>Step 7:</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 1200.</p>
27 <p><strong>Step 8:</strong>Now we need to find the new divisor, which is 176 because 176 x 7 = 1232.</p>
26 <p><strong>Step 8:</strong>Now we need to find the new divisor, which is 176 because 176 x 7 = 1232.</p>
28 <p><strong>Step 9:</strong>Subtracting 1232 from 1200 gives the result of -32.</p>
27 <p><strong>Step 9:</strong>Subtracting 1232 from 1200 gives the result of -32.</p>
29 <p><strong>Step 10:</strong>Now the quotient is 17.6.</p>
28 <p><strong>Step 10:</strong>Now the quotient is 17.6.</p>
30 <p><strong>Step 11:</strong>Continue doing these steps until we get two numbers after the decimal point. Suppose if there are no decimal values, continue till the remainder is zero.</p>

36 <p><strong>Step 2:</strong>Now we need to apply the<a>formula</a>: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square). Applying the formula, (312 - 289) / (324 - 289) = 0.66.</p>
