780655 ÷ 9 
We want to figure out the number of times 780655 can be divided by 9.

Going ahead to step 1:
If we divide 7 by 9, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 9

Going ahead to step 2:
78 divided by 9 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 72 from 78 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

On to step 3:
60 divided by 9 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 54 from 60 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 9

Step 4:
9 can be fit into 66 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 867.0
If we subtract 63 from 66, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Advancing to step 5:
When dividing 35 by 9, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 8673.0
Deduct 27 from 35 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 9

Step 6:
9 goes into 85 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 86739.0
Deduct 81 from 85 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 86739.4
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
9 goes into 40 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 86739.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 86739.44 with a remainder of 0.004.
