78982719 ÷ 9 
We want to figure out the number of times 78982719 can be divided by 9.

Advancing to step 1:
9 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Let's proceed to step 2:
If we divide 78 by 9, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 72 away from 78, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 9

Advancing to step 3:
If we divide 69 by 9, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 63 from 69 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 9

Step 4:
68 divided by 9 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
The remainder is 5 after subtracting 63 from 68.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 9

On to step 5:
The number 9 fits into 52 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 8775.0
Subtracting 45 from 52 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 9

Let's proceed to step 6:
When dividing 77 by 9, we get 8 with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 87758.0
If we take 72 away from 77, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 9

Step 7:
9 goes into 51 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 877585.0
Subtracting 45 from 51 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

On to step 8:
9 can be fit into 69 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8775857.0
Subtract 63 from 69 to 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.

On to step 9:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 8775857.6
If we subtract 54 from 60, 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.

Advancing to step 10:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 8775857.66
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.

Our division results in 8775857.66 with a remaining 0.006.
