Record the quotient 3 as the next digit in the result. 
Result so far: 4953.0
Subtract 2517 from 2531 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 839

On to step 8:
If we divide 147 by 839, we get 0 and a remainder of 147.
Use 0 as the next digit of our solution. 
Result so far: 49530.0
The remainder is 147 after subtracting 0 from 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 9:
1470 divided by 839 is 1 with a remainder of 631.
Write down 1 as next digit of the result. 
Result so far: 49530.1
If we subtract 839 from 1470, we get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 10:
If we divide 6310 by 839, we get 7 and a remainder of 437.
Put 7 as the next digit of the answer. 
Result so far: 49530.17
If we subtract 5873 from 6310, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Put 5 as the next digit of the answer. 
Result so far: 49530.175
Deduct 4195 from 4370 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
The number 839 fits into 1750 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 49530.1752
Deduct 1678 from 1750 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
720 divided by 839 is 0 with a remainder of 720.
The next digit of our result is 0. 
Result so far: 49530.1752
Subtracting 0 from 720 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 14:
839 can be fit into 7200 8 times, resulting in a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 49530.175208
If we take 6712 away from 7200, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 15:
When dividing 4880 by 839, we get 5 with a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 49530.1752085
If we subtract 4195 from 4880, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 16:
If we divide 6850 by 839, we get 8 and a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 49530.17520858
If we subtract 6712 from 6850, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The quotient of the division is 49530.17520858, and the remainder is 1.38e-07.
