Moving on to step 5:
4301 divided by 859 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 4295 from 4301 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 859

Moving on to step 6:
62 divided by 859 is 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 1050.0
The remainder is 62 after subtracting 0 from 62.

Moving on to step 7:
The number 859 fits into 626 0 times, leaving a remainder of 626.
The next digit of our result is 0. 
Result so far: 10500.0
Subtracting 0 from 626 leaves us with 626.
Fetch the next digit (0) from the dividend, attach it to 626 and continue: 6260 / 859

Step 8:
859 goes into 6260 7 times with a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 105007.0
The remainder is 247 after subtracting 6013 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 9:
859 goes into 2470 2 times with a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 105007.2
Subtracting 1718 from 2470 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 10:
7520 divided by 859 is 8 with a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 105007.28
If we take 6872 away from 7520, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 11:
When dividing 6480 by 859, we get 7 with a remainder of 467.
Put 7 as the next digit of the answer. 
Result so far: 105007.287
Subtracting 6013 from 6480 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Step 12:
859 goes into 4670 5 times with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 105007.2875
The remainder is 375 after subtracting 4295 from 4670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 13:
3750 divided by 859 is 4 with a remainder of 314.
Write down 4 as next digit of the result. 
Result so far: 105007.28754
Subtract 3436 from 3750 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 14:
When dividing 3140 by 859, we get 3 with a remainder of 563.
The number 3 becomes the next digit in our result. 
Result so far: 105007.287543
Subtracting 2577 from 3140 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Moving on to step 15:
859 can be fit into 5630 6 times, resulting in a remainder of 476.
The next digit of our result is 6. 
Result so far: 105007.2875436
If we take 5154 away from 5630, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 16:
859 goes into 4760 5 times with a remainder of 465.
The next digit of our result is 5. 
Result so far: 105007.28754365
Deduct 4295 from 4760 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

In conclusion, the division gives 105007.28754365 with a balance of 4.65e-07.
