Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 429 and we're left with 429.
Append the next digit (9) from the dividend to 429 and continue with: 4299 / 871

Moving on to step 5:
871 can be fit into 4299 4 times, resulting in a remainder of 815.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 3484 from 4299 and we're left with 815.
Include the next digit (5) from the dividend after 815, then repeat: 8155 / 871

Moving on to step 6:
When dividing 8155 by 871, we get 9 with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 1049.0
If we take 7839 away from 8155, we end up with 316.
Append the next digit (7) from the dividend to 316 and continue with: 3167 / 871

Advancing to step 7:
3167 divided by 871 is 3 with a remainder of 554.
Put 3 as the next digit of the answer. 
Result so far: 10493.0
Subtract 2613 from 3167 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 8:
871 goes into 5540 6 times with a remainder of 314.
Use 6 as the next digit of our solution. 
Result so far: 10493.6
If we subtract 5226 from 5540, we 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 9:
If we divide 3140 by 871, we get 3 and a remainder of 527.
Use 3 as the next digit of our solution. 
Result so far: 10493.63
The remainder is 527 after subtracting 2613 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Going ahead to step 10:
When dividing 5270 by 871, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 10493.636
If we take 5226 away from 5270, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
If we divide 440 by 871, we get 0 and a remainder of 440.
The next digit of our result is 0. 
Result so far: 10493.636
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
871 goes into 4400 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 10493.63605
The remainder is 45 after subtracting 4355 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
When dividing 450 by 871, we get 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 10493.63605
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 14:
If we divide 4500 by 871, we get 5 and a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 10493.6360505
The remainder is 145 after subtracting 4355 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 15:
The number 871 fits into 1450 1 times, leaving a remainder of 579.
Use 1 as the next digit of our solution. 
Result so far: 10493.63605051
Subtracting 871 from 1450 leaves us with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Our division results in 10493.63605051 with a remaining 5.79e-07.
