On to step 5:
4616 divided by 871 is 5 with a remainder of 261.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 4355 away from 4616, we end up with 261.
Take the next digit (5) from the dividend and append it to 261, then repeat: 2615 / 871

Moving on to step 6:
871 can be fit into 2615 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
The remainder is 2 after subtracting 2613 from 2615.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 871

Let's proceed to step 7:
The number 871 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 7530.0
If we subtract 0 from 21, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 871

Let's proceed to step 8:
871 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 75300.0
If we take 0 away from 215, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 9:
The number 871 fits into 2150 2 times, leaving a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 75300.2
Subtracting 1742 from 2150 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
The number 871 fits into 4080 4 times, leaving a remainder of 596.
Use 4 as the next digit of our solution. 
Result so far: 75300.24
Subtract 3484 from 4080 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 11:
871 goes into 5960 6 times with a remainder of 734.
Use 6 as the next digit of our solution. 
Result so far: 75300.246
Subtract 5226 from 5960 to get 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

On to step 12:
The number 871 fits into 7340 8 times, leaving a remainder of 372.
Put 8 as the next digit of the answer. 
Result so far: 75300.2468
If we take 6968 away from 7340, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 13:
The number 871 fits into 3720 4 times, leaving a remainder of 236.
The next digit of our result is 4. 
Result so far: 75300.24684
Subtracting 3484 from 3720 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 14:
871 can be fit into 2360 2 times, resulting in a remainder of 618.
The next digit of our result is 2. 
Result so far: 75300.246842
Subtract 1742 from 2360 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 15:
6180 divided by 871 is 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 75300.2468427
The remainder is 83 after subtracting 6097 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 16:
830 divided by 871 is 0 with a remainder of 830.
Write down 0 as next digit of the result. 
Result so far: 75300.2468427
If we subtract 0 from 830, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

The final result is 75300.2468427 with a remainder of 8.3e-07.
