<p><strong>Step 1:</strong>To begin with, we need to group the numbers from right to left. In the case of 777, we need to group it as 77 and 7.</p>

<p><strong>Step 2:</strong>Now we need to find n whose square is<a>less than</a>or equal to 7. We can say n is ‘2’ because 2 x 2 is less than or equal to 7. Now the<a>quotient</a>is 2; after subtracting 4 from 7, the<a>remainder</a>is 3.</p>

<p><strong>Step 3:</strong>Now let us bring down 77, which is the new<a>dividend</a>. Add the old<a>divisor</a>with the same number: 2 + 2 = 4, which will be our new divisor.</p>

<p><strong>Step 4:</strong>The new divisor will be 40 (as 4 becomes 40 by adding a digit). We need to find the value of n such that 40n x n ≤ 377.</p>

<p><strong>Step 5:</strong>Let's try n = 9. Now 409 x 9 = 3681.</p>

<p><strong>Step 5:</strong>Let's try n = 9. Now 409 x 9 = 3681.</p>

<p><strong>Step 6:</strong>Subtract 3681 from 3770, the difference is 89, and the quotient is 27.9.</p>

<p><strong>Step 6:</strong>Subtract 3681 from 3770, the difference is 89, and the quotient is 27.9.</p>
8
<p><strong>Step 7:</strong>Since the dividend is less than the divisor, we need to add a<a>decimal</a>point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 8900.</p>

<p><strong>Step 7:</strong>Since the dividend is less than the divisor, we need to add a<a>decimal</a>point. Adding the decimal point allows us to add two zeroes to the dividend. Now the new dividend is 8900.</p>

<p><strong>Step 8:</strong>Now we need to find the new divisor, which is 558 because 558 x 8 = 4464.</p>

<p><strong>Step 8:</strong>Now we need to find the new divisor, which is 558 because 558 x 8 = 4464.</p>

<p><strong>Step 9:</strong>Subtracting 4464 from 8900, we get the result 4436.</p>

<p><strong>Step 9:</strong>Subtracting 4464 from 8900, we get the result 4436.</p>
