Put 3 as the next digit of the answer. 
Result so far: 553.0
Subtracting 2727 from 3539 leaves us with 812.
Append the next digit (7) from the dividend to 812 and continue with: 8127 / 909

Advancing to step 7:
When dividing 8127 by 909, we get 8 with a remainder of 855.
Record the quotient 8 as the next digit in the result. 
Result so far: 5538.0
The remainder is 855 after subtracting 7272 from 8127.
Append the next digit (9) from the dividend to 855 and continue with: 8559 / 909

Moving on to step 8:
The number 909 fits into 8559 9 times, leaving a remainder of 378.
Use 9 as the next digit of our solution. 
Result so far: 55389.0
The remainder is 378 after subtracting 8181 from 8559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 9:
909 goes into 3780 4 times with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 55389.4
The remainder is 144 after subtracting 3636 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
909 can be fit into 1440 1 times, resulting in a remainder of 531.
The number 1 becomes the next digit in our result. 
Result so far: 55389.41
If we take 909 away from 1440, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 11:
909 can be fit into 5310 5 times, resulting in a remainder of 765.
Write down 5 as next digit of the result. 
Result so far: 55389.415
Subtracting 4545 from 5310 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Going ahead to step 12:
909 goes into 7650 8 times with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 55389.4158
If we take 7272 away from 7650, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 13:
909 can be fit into 3780 4 times, resulting in a remainder of 144.
The next digit of our result is 4. 
Result so far: 55389.41584
If we subtract 3636 from 3780, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
909 can be fit into 1440 1 times, resulting in a remainder of 531.
Put 1 as the next digit of the answer. 
Result so far: 55389.415841
The remainder is 531 after subtracting 909 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 15:
The number 909 fits into 5310 5 times, leaving a remainder of 765.
Put 5 as the next digit of the answer. 
Result so far: 55389.4158415
Subtracting 4545 from 5310 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 16:
If we divide 7650 by 909, we get 8 and a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 55389.41584158
Deduct 7272 from 7650 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.
