14904927 divided by 991 
The aim is to understand the frequency of 991 in 14904927.

Let's proceed to step 1:
If we divide 1 by 991, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 991

Step 2:
991 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 991

Advancing to step 3:
991 can be fit into 149 0 times, resulting in a remainder of 149.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 149, we get 149.
Take the next digit (0) from the dividend and append it to 149, then repeat: 1490 / 991

Advancing to step 4:
991 goes into 1490 1 times with a remainder of 499.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 991 from 1490 and we're left with 499.
Fetch the next digit (4) from the dividend, attach it to 499 and continue: 4994 / 991

Going ahead to step 5:
991 can be fit into 4994 5 times, resulting in a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 4955 from 4994, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 991

On to step 6:
The number 991 fits into 399 0 times, leaving a remainder of 399.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we subtract 0 from 399, we get 399.
Include the next digit (2) from the dividend after 399, then repeat: 3992 / 991

Advancing to step 7:
The number 991 fits into 3992 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1504.0
Subtract 3964 from 3992 to get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 991

Let's proceed to step 8:
991 can be fit into 287 0 times, resulting in a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 15040.0
Deduct 0 from 287 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 9:
When dividing 2870 by 991, we get 2 with a remainder of 888.
Write down 2 as next digit of the result. 
Result so far: 15040.2
Subtracting 1982 from 2870 leaves us with 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Advancing to step 10:
If we divide 8880 by 991, we get 8 and a remainder of 952.
Use 8 as the next digit of our solution. 
Result so far: 15040.28
Subtract 7928 from 8880 to get 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

Advancing to step 11:
The number 991 fits into 9520 9 times, leaving a remainder of 601.
Use 9 as the next digit of our solution. 
Result so far: 15040.289
Subtract 8919 from 9520 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 12:
6010 divided by 991 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 15040.2896
If we subtract 5946 from 6010, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 991, we get 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 15040.2896
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
991 can be fit into 6400 6 times, resulting in a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 15040.289606
If we subtract 5946 from 6400, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 15:
When dividing 4540 by 991, we get 4 with a remainder of 576.
The next digit of our result is 4. 
Result so far: 15040.2896064
The remainder is 576 after subtracting 3964 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 16:
The number 991 fits into 5760 5 times, leaving a remainder of 805.
Use 5 as the next digit of our solution. 
Result so far: 15040.28960645
If we take 4955 away from 5760, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

The final outcome is 15040.28960645, with a leftover of 8.05e-07.
