Let's divide 780866 by 9
We want to figure out the number of times 780866 can be divided by 9.

Moving on to step 1:
7 divided by 9 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Moving on to step 2:
When dividing 78 by 9, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 72 away from 78, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 9

On to step 3:
When dividing 60 by 9, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we take 54 away from 60, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 9

Let's proceed to step 4:
9 goes into 68 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 867.0
If we take 63 away from 68, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 9

On to step 5:
9 goes into 56 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 8676.0
Deduct 54 from 56 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 9

Step 6:
When dividing 26 by 9, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 86762.0
Subtract 18 from 26 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 86762.8
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 9, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 86762.88
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 86762.88, with a leftover of 0.008.
