91880628 ÷ 9 
We want to divide 91880628 by 9.

On to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 9 from 9 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 9

On to step 2:
1 divided by 9 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 9

On to step 3:
The number 9 fits into 18 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 9

Going ahead to step 4:
When dividing 8 by 9, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 1020.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 9

Moving on to step 5:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 10208.0
If we subtract 72 from 80, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 9

Let's proceed to step 6:
9 can be fit into 86 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 102089.0
The remainder is 5 after subtracting 81 from 86.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 9

Going ahead to step 7:
9 can be fit into 52 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 1020895.0
Deduct 45 from 52 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Step 8:
78 divided by 9 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10208958.0
Subtracting 72 from 78 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 9:
9 can be fit into 60 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 10208958.6
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.

Step 10:
When dividing 60 by 9, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 10208958.66
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.

The final outcome is 10208958.66, with a leftover of 0.006.
