871831 ÷ 18 
We want to divide 871831 by 18.

Going ahead to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 18

On to step 2:
The number 18 fits into 87 4 times, leaving a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 72 from 87 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 18

Moving on to step 3:
18 goes into 151 8 times with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 7 after subtracting 144 from 151.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 18

Advancing to step 4:
The number 18 fits into 78 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
If we take 72 away from 78, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 18

Let's proceed to step 5:
18 goes into 63 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 4843.0
If we subtract 54 from 63, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 18

On to step 6:
18 can be fit into 91 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 48435.0
If we subtract 90 from 91, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 18 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 48435.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 48435.05
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 48435.055
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 48435.055 with a balance of 0.001.
