On to step 5:
When dividing 7016 by 839, we get 8 with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 6712 from 7016, we get 304.
Append the next digit (5) from the dividend to 304 and continue with: 3045 / 839

Moving on to step 6:
If we divide 3045 by 839, we get 3 and a remainder of 528.
Write down 3 as next digit of the result. 
Result so far: 483.0
If we subtract 2517 from 3045, we get 528.
Fetch the next digit (1) from the dividend, attach it to 528 and continue: 5281 / 839

Let's proceed to step 7:
If we divide 5281 by 839, we get 6 and a remainder of 247.
Put 6 as the next digit of the answer. 
Result so far: 4836.0
Subtract 5034 from 5281 to get 247.
Fetch the next digit (1) from the dividend, attach it to 247 and continue: 2471 / 839

Advancing to step 8:
2471 divided by 839 is 2 with a remainder of 793.
The number 2 becomes the next digit in our result. 
Result so far: 48362.0
Subtracting 1678 from 2471 leaves us with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Step 9:
839 can be fit into 7930 9 times, resulting in a remainder of 379.
Use 9 as the next digit of our solution. 
Result so far: 48362.9
Subtracting 7551 from 7930 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 10:
When dividing 3790 by 839, we get 4 with a remainder of 434.
The next digit of our result is 4. 
Result so far: 48362.94
If we subtract 3356 from 3790, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 11:
The number 839 fits into 4340 5 times, leaving a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 48362.945
The remainder is 145 after subtracting 4195 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
When dividing 1450 by 839, we get 1 with a remainder of 611.
Put 1 as the next digit of the answer. 
Result so far: 48362.9451
If we take 839 away from 1450, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 13:
If we divide 6110 by 839, we get 7 and a remainder of 237.
Use 7 as the next digit of our solution. 
Result so far: 48362.94517
If we subtract 5873 from 6110, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 14:
839 goes into 2370 2 times with a remainder of 692.
Use 2 as the next digit of our solution. 
Result so far: 48362.945172
Subtracting 1678 from 2370 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Going ahead to step 15:
6920 divided by 839 is 8 with a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 48362.9451728
If we take 6712 away from 6920, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 16:
839 goes into 2080 2 times with a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 48362.94517282
Subtract 1678 from 2080 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 48362.94517282 with a remainder of 4.02e-07.
