78909 divided by 9 
We want to figure out the number of times 78909 can be divided by 9.

On to step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 9

Moving on to step 2:
9 goes into 78 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 72 from 78 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 9

On to step 3:
When dividing 69 by 9, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 63 from 69 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

Moving on to step 4:
9 goes into 60 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 876.0
Subtracting 54 from 60 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 9

Let's proceed to step 5:
9 goes into 69 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8767.0
If we subtract 63 from 69, we 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.

Step 6:
60 divided by 9 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 8767.6
Subtracting 54 from 60 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.

Moving on to step 7:
60 divided by 9 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 8767.66
Subtracting 54 from 60 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.

The quotient of the division is 8767.66, and the remainder is 0.006.
