860591 divided by 9 
Let's see how many times 9 fits into 860591.

Advancing to step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 9

On to step 2:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 5 after subtracting 81 from 86.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 9

On to step 3:
If we divide 50 by 9, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 95.0
Deduct 45 from 50 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 9

Step 4:
9 can be fit into 55 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 956.0
If we take 54 away from 55, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 9

Moving on to step 5:
9 goes into 19 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 9562.0
If we take 18 away from 19, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Let's proceed to step 6:
If we divide 11 by 9, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 95621.0
The remainder is 2 after subtracting 9 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 95621.2
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 95621.22
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 95621.22 with a balance of 0.002.
