Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
When dividing 490 by 77, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1138.36
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 1138.363
If we subtract 231 from 280, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
If we divide 490 by 77, we get 6 and a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1138.3636
Subtracting 462 from 490 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 1138.36363
If we take 231 away from 280, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
77 can be fit into 490 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1138.363636
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 77 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 1138.3636363
Subtracting 231 from 280 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 13:
When dividing 490 by 77, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1138.36363636
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.
