Let's divide 297476 by 91
The aim is to understand the frequency of 91 in 297476.

Step 1:
When dividing 2 by 91, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 91

Moving on to step 2:
91 can be fit into 29 0 times, resulting in a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 91

Step 3:
The number 91 fits into 297 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 24 after subtracting 273 from 297.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 91

Let's proceed to step 4:
If we divide 244 by 91, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 182 from 244 and we're left with 62.
Bring next digit (7) of the dividend behind the 62 and repeat the process: 627 / 91

Moving on to step 5:
When dividing 627 by 91, we get 6 with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 326.0
Subtracting 546 from 627 leaves us with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 91

Let's proceed to step 6:
91 can be fit into 816 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 3268.0
Subtract 728 from 816 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
880 divided by 91 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 3268.9
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
91 can be fit into 610 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 3268.96
Subtract 546 from 610 to 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.

Step 9:
640 divided by 91 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 3268.967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
The number 91 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3268.967
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
91 can be fit into 300 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3268.96703
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
If we divide 270 by 91, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 3268.967032
Subtracting 182 from 270 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 3268.9670329
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
91 can be fit into 610 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3268.96703296
Subtract 546 from 610 to 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.

After the division, we end up with 3268.96703296 and a remainder of 6.4e-08.
