We divide 91116858 by 312
We want to figure out the number of times 91116858 can be divided by 312.

On to step 1:
The number 312 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 312

On to step 2:
If we divide 91 by 312, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 312

On to step 3:
312 goes into 911 2 times with a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 287 after subtracting 624 from 911.
Grab the next digit (1) from the dividend, add it to 287, then carry on: 2871 / 312

Advancing to step 4:
2871 divided by 312 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 2808 away from 2871, we end up with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 312

On to step 5:
636 divided by 312 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
Deduct 624 from 636 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 312

Moving on to step 6:
When dividing 128 by 312, we get 0 with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 2920.0
Deduct 0 from 128 and we're left with 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 312

Step 7:
312 goes into 1285 4 times with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 29204.0
The remainder is 37 after subtracting 1248 from 1285.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 312

Going ahead to step 8:
312 can be fit into 378 1 times, resulting in a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 292041.0
Subtract 312 from 378 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
312 can be fit into 660 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 292041.2
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
312 goes into 360 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 292041.21
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
If we divide 480 by 312, we get 1 and a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 292041.211
Subtracting 312 from 480 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 292041.211, and the remainder is 0.0168.
