We divide 23269721 by 991
The aim is to understand the frequency of 991 in 23269721.

Step 1:
2 divided by 991 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 991

Step 2:
991 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 991

On to step 3:
232 divided by 991 is 0 with a remainder of 232.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 232, we get 232.
Take the next digit (6) from the dividend and append it to 232, then repeat: 2326 / 991

Let's proceed to step 4:
2326 divided by 991 is 2 with a remainder of 344.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 344 after subtracting 1982 from 2326.
Take the next digit (9) from the dividend and append it to 344, then repeat: 3449 / 991

Let's proceed to step 5:
991 goes into 3449 3 times with a remainder of 476.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 2973 from 3449 leaves us with 476.
Append the next digit (7) from the dividend to 476 and continue with: 4767 / 991

On to step 6:
991 goes into 4767 4 times with a remainder of 803.
The next digit of our result is 4. 
Result so far: 234.0
Subtracting 3964 from 4767 leaves us with 803.
Grab the next digit (2) from the dividend, add it to 803, then carry on: 8032 / 991

Advancing to step 7:
The number 991 fits into 8032 8 times, leaving a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 2348.0
If we take 7928 away from 8032, we end up with 104.
Take the next digit (1) from the dividend and append it to 104, then repeat: 1041 / 991

Going ahead to step 8:
When dividing 1041 by 991, we get 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 23481.0
Subtracting 991 from 1041 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
When dividing 500 by 991, we get 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 23481.0
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
991 can be fit into 5000 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 23481.05
If we take 4955 away from 5000, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
991 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 23481.05
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 12:
991 can be fit into 4500 4 times, resulting in a remainder of 536.
Record the quotient 4 as the next digit in the result. 
Result so far: 23481.0504
Deduct 3964 from 4500 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 13:
When dividing 5360 by 991, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 23481.05045
The remainder is 405 after subtracting 4955 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 14:
When dividing 4050 by 991, we get 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 23481.050454
If we take 3964 away from 4050, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 15:
860 divided by 991 is 0 with a remainder of 860.
Use 0 as the next digit of our solution. 
Result so far: 23481.050454
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Step 16:
991 can be fit into 8600 8 times, resulting in a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 23481.05045408
Deduct 7928 from 8600 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Our division results in 23481.05045408 with a remaining 6.72e-07.
