866031 ÷ 9 
Let's see how many times 9 fits into 866031.

Advancing to step 1:
9 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 9

Let's proceed to step 2:
9 can be fit into 86 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 81 away from 86, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 9

Step 3:
The number 9 fits into 56 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 2 after subtracting 54 from 56.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 9

Moving on to step 4:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 962.0
Deduct 18 from 20 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 9

Let's proceed to step 5:
If we divide 23 by 9, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 9622.0
If we take 18 away from 23, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 9

Step 6:
When dividing 51 by 9, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 96225.0
The remainder is 6 after subtracting 45 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
9 can be fit into 60 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 96225.6
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
9 can be fit into 60 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 96225.66
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 96225.66 with a remainder of 0.006.
