Going ahead to step 5:
872 can be fit into 4983 5 times, resulting in a remainder of 623.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 4360 from 4983 and we're left with 623.
Append the next digit (5) from the dividend to 623 and continue with: 6235 / 872

Step 6:
872 can be fit into 6235 7 times, resulting in a remainder of 131.
Use 7 as the next digit of our solution. 
Result so far: 457.0
Subtracting 6104 from 6235 leaves us with 131.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 872

Moving on to step 8:
4400 divided by 872 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 4571.5
Subtract 4360 from 4400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 872 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 4571.5
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
If we divide 4000 by 872, we get 4 and a remainder of 512.
Use 4 as the next digit of our solution. 
Result so far: 4571.504
Deduct 3488 from 4000 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 11:
The number 872 fits into 5120 5 times, leaving a remainder of 760.
The next digit of our result is 5. 
Result so far: 4571.5045
If we subtract 4360 from 5120, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 12:
If we divide 7600 by 872, we get 8 and a remainder of 624.
Put 8 as the next digit of the answer. 
Result so far: 4571.50458
If we subtract 6976 from 7600, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 13:
872 goes into 6240 7 times with a remainder of 136.
Use 7 as the next digit of our solution. 
Result so far: 4571.504587
If we subtract 6104 from 6240, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 14:
872 goes into 1360 1 times with a remainder of 488.
Record the quotient 1 as the next digit in the result. 
Result so far: 4571.5045871
Subtract 872 from 1360 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 15:
872 goes into 4880 5 times with a remainder of 520.
Write down 5 as next digit of the result. 
Result so far: 4571.50458715
The remainder is 520 after subtracting 4360 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 4571.50458715 with a balance of 5.2e-07.
