78508834 divided by 9 
We want to figure out the number of times 78508834 can be divided by 9.

Let's proceed to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 9

Advancing to step 2:
9 can be fit into 78 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 72 from 78 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 9

Going ahead to step 3:
9 goes into 65 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 2 after subtracting 63 from 65.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 9

Going ahead to step 4:
9 goes into 20 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 872.0
The remainder is 2 after subtracting 18 from 20.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

On to step 5:
9 goes into 28 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 8723.0
If we take 27 away from 28, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 9

Advancing to step 6:
9 can be fit into 18 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 87232.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Let's proceed to step 7:
3 divided by 9 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 872320.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 9

Let's proceed to step 8:
If we divide 34 by 9, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8723203.0
Deduct 27 from 34 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 8723203.7
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 9, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 8723203.77
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 8723203.77 with a remaining 0.007.
