<p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 191, we need to group it as 91 and 1.</p>

<p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 1. We can say n is '1' because 1 × 1 is less than or equal to 1. Now the<a>quotient</a>is 1; after subtracting 1 - 1, the<a>remainder</a>is 0.</p>

<p><strong>Step 4:</strong>The new divisor will be the sum of the dividend and quotient. Now we get 2n as the new divisor; we need to find the value of n.</p>

<p><strong>Step 5:</strong>The next step is finding 2n × n ≤ 91. Let us consider n as 4, now 2 × 4 × 4 = 32.</p>

<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 5900.</p>
