871573 divided by 9 
Our goal is to divide 871573 by 9.

Advancing to step 1:
8 divided by 9 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 9

Advancing to step 2:
If we divide 87 by 9, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 6 after subtracting 81 from 87.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 9

Advancing to step 3:
9 goes into 61 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 54 away from 61, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 9

On to step 4:
9 can be fit into 75 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 968.0
If we subtract 72 from 75, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 9

On to step 5:
9 goes into 37 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 9684.0
Deduct 36 from 37 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 9

Moving on to step 6:
9 can be fit into 13 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 96841.0
If we subtract 9 from 13, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 9, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 96841.4
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 9 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 96841.44
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 96841.44 with a remaining 0.004.
