Let's divide 90414272 by 991
We want to divide 90414272 by 991.

Going ahead to step 1:
991 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 991

Moving on to step 2:
The number 991 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 991

On to step 3:
904 divided by 991 is 0 with a remainder of 904.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 904 and we're left with 904.
Include the next digit (1) from the dividend after 904, then repeat: 9041 / 991

Going ahead to step 4:
When dividing 9041 by 991, we get 9 with a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 122 after subtracting 8919 from 9041.
Fetch the next digit (4) from the dividend, attach it to 122 and continue: 1224 / 991

On to step 5:
1224 divided by 991 is 1 with a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we take 991 away from 1224, we end up with 233.
Include the next digit (2) from the dividend after 233, then repeat: 2332 / 991

On to step 6:
2332 divided by 991 is 2 with a remainder of 350.
Put 2 as the next digit of the answer. 
Result so far: 912.0
If we subtract 1982 from 2332, we get 350.
Grab the next digit (7) from the dividend, add it to 350, then carry on: 3507 / 991

Step 7:
If we divide 3507 by 991, we get 3 and a remainder of 534.
Write down 3 as next digit of the result. 
Result so far: 9123.0
Subtracting 2973 from 3507 leaves us with 534.
Bring next digit (2) of the dividend behind the 534 and repeat the process: 5342 / 991

Advancing to step 8:
When dividing 5342 by 991, we get 5 with a remainder of 387.
The next digit of our result is 5. 
Result so far: 91235.0
Deduct 4955 from 5342 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 9:
3870 divided by 991 is 3 with a remainder of 897.
The next digit of our result is 3. 
Result so far: 91235.3
Subtract 2973 from 3870 to get 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8970, and continue the process.

On to step 10:
991 goes into 8970 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 91235.39
The remainder is 51 after subtracting 8919 from 8970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
The number 991 fits into 510 0 times, leaving a remainder of 510.
The next digit of our result is 0. 
Result so far: 91235.39
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 12:
5100 divided by 991 is 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 91235.3905
Subtracting 4955 from 5100 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 13:
When dividing 1450 by 991, we get 1 with a remainder of 459.
Record the quotient 1 as the next digit in the result. 
Result so far: 91235.39051
If we take 991 away from 1450, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 14:
991 goes into 4590 4 times with a remainder of 626.
The next digit of our result is 4. 
Result so far: 91235.390514
If we take 3964 away from 4590, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 15:
When dividing 6260 by 991, we get 6 with a remainder of 314.
The next digit of our result is 6. 
Result so far: 91235.3905146
Subtracting 5946 from 6260 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 16:
The number 991 fits into 3140 3 times, leaving a remainder of 167.
The next digit of our result is 3. 
Result so far: 91235.39051463
If we subtract 2973 from 3140, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

The final outcome is 91235.39051463, with a leftover of 1.67e-07.
