866355 divided by 9 
We want to divide 866355 by 9.

Going ahead to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 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 goes into 86 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 81 from 86 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 9

Let's proceed to step 3:
The number 9 fits into 56 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we take 54 away from 56, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 9

Advancing to step 4:
When dividing 23 by 9, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 962.0
Deduct 18 from 23 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 9

Step 5:
When dividing 55 by 9, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 9626.0
Deduct 54 from 55 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 9

On to step 6:
9 goes into 15 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 96261.0
Subtracting 9 from 15 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
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: 96261.6
If we take 54 away from 60, we end up with 6.
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:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 96261.66
If we take 54 away from 60, we end up with 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 quotient of the division is 96261.66, and the remainder is 0.006.
