Moving on to step 5:
1606 divided by 539 is 2 with a remainder of 528.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 1078 from 1606 to get 528.
Fetch the next digit (4) from the dividend, attach it to 528 and continue: 5284 / 539

Going ahead to step 6:
The number 539 fits into 5284 9 times, leaving a remainder of 433.
The next digit of our result is 9. 
Result so far: 1229.0
Subtract 4851 from 5284 to get 433.
Append the next digit (9) from the dividend to 433 and continue with: 4339 / 539

Advancing to step 7:
539 can be fit into 4339 8 times, resulting in a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 12298.0
Subtract 4312 from 4339 to get 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 539

On to step 8:
When dividing 277 by 539, we get 0 with a remainder of 277.
The next digit of our result is 0. 
Result so far: 122980.0
If we subtract 0 from 277, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 9:
2770 divided by 539 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 122980.5
Subtracting 2695 from 2770 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
750 divided by 539 is 1 with a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 122980.51
Subtract 539 from 750 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
If we divide 2110 by 539, we get 3 and a remainder of 493.
The number 3 becomes the next digit in our result. 
Result so far: 122980.513
Subtract 1617 from 2110 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Let's proceed to step 12:
The number 539 fits into 4930 9 times, leaving a remainder of 79.
The next digit of our result is 9. 
Result so far: 122980.5139
Subtract 4851 from 4930 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
539 goes into 790 1 times with a remainder of 251.
Write down 1 as next digit of the result. 
Result so far: 122980.51391
Deduct 539 from 790 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 14:
The number 539 fits into 2510 4 times, leaving a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 122980.513914
The remainder is 354 after subtracting 2156 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 15:
539 goes into 3540 6 times with a remainder of 306.
Write down 6 as next digit of the result. 
Result so far: 122980.5139146
Deduct 3234 from 3540 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 16:
When dividing 3060 by 539, we get 5 with a remainder of 365.
The next digit of our result is 5. 
Result so far: 122980.51391465
Deduct 2695 from 3060 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final result is 122980.51391465 with a remainder of 3.65e-07.
