We're dividing 89079552 by 991 
The aim is to understand the frequency of 991 in 89079552.

Step 1:
8 divided by 991 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 991

Going ahead to step 2:
991 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 991

Advancing to step 3:
The number 991 fits into 890 0 times, leaving a remainder of 890.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 890 leaves us with 890.
Take the next digit (7) from the dividend and append it to 890, then repeat: 8907 / 991

Moving on to step 4:
The number 991 fits into 8907 8 times, leaving a remainder of 979.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7928 from 8907 leaves us with 979.
Append the next digit (9) from the dividend to 979 and continue with: 9799 / 991

Advancing to step 5:
991 can be fit into 9799 9 times, resulting in a remainder of 880.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 8919 from 9799 leaves us with 880.
Grab the next digit (5) from the dividend, add it to 880, then carry on: 8805 / 991

Step 6:
991 can be fit into 8805 8 times, resulting in a remainder of 877.
The next digit of our result is 8. 
Result so far: 898.0
Subtracting 7928 from 8805 leaves us with 877.
Fetch the next digit (5) from the dividend, attach it to 877 and continue: 8775 / 991

Going ahead to step 7:
991 goes into 8775 8 times with a remainder of 847.
The number 8 becomes the next digit in our result. 
Result so far: 8988.0
If we subtract 7928 from 8775, we get 847.
Take the next digit (2) from the dividend and append it to 847, then repeat: 8472 / 991

Moving on to step 8:
If we divide 8472 by 991, we get 8 and a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 89888.0
If we subtract 7928 from 8472, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 9:
If we divide 5440 by 991, we get 5 and a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 89888.5
Subtract 4955 from 5440 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 10:
991 can be fit into 4850 4 times, resulting in a remainder of 886.
The number 4 becomes the next digit in our result. 
Result so far: 89888.54
If we subtract 3964 from 4850, we get 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Going ahead to step 11:
991 goes into 8860 8 times with a remainder of 932.
Put 8 as the next digit of the answer. 
Result so far: 89888.548
If we subtract 7928 from 8860, we get 932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9320, and continue the process.

Going ahead to step 12:
When dividing 9320 by 991, we get 9 with a remainder of 401.
The next digit of our result is 9. 
Result so far: 89888.5489
The remainder is 401 after subtracting 8919 from 9320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 13:
When dividing 4010 by 991, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 89888.54894
The remainder is 46 after subtracting 3964 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
991 can be fit into 460 0 times, resulting in a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 89888.54894
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 15:
991 can be fit into 4600 4 times, resulting in a remainder of 636.
Record the quotient 4 as the next digit in the result. 
Result so far: 89888.5489404
Subtracting 3964 from 4600 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 16:
6360 divided by 991 is 6 with a remainder of 414.
Put 6 as the next digit of the answer. 
Result so far: 89888.54894046
If we subtract 5946 from 6360, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The quotient of the division is 89888.54894046, and the remainder is 4.14e-07.
