860430 divided by 9 
We want to divide 860430 by 9.

On to step 1:
8 divided by 9 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 9

Step 2:
9 can be fit into 86 9 times, resulting in 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.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 9

On to step 3:
If we divide 50 by 9, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 45 away from 50, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 9

Moving on to step 4:
When dividing 54 by 9, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 956.0
If we subtract 54 from 54, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 9

Going ahead to step 5:
3 divided by 9 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 9560.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

Step 6:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 95603.0
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 9 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 95603.3
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
9 goes into 30 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 95603.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 95603.33, with a leftover of 0.003.
