We look at the division of 888491 by 91 
The aim is to understand the frequency of 91 in 888491.

Moving on to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 91

Step 2:
91 can be fit into 88 0 times, resulting in a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Bring next digit (8) of the dividend behind the 88 and repeat the process: 888 / 91

Going ahead to step 3:
The number 91 fits into 888 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 69 after subtracting 819 from 888.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 91

On to step 4:
When dividing 694 by 91, we get 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 57 after subtracting 637 from 694.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 91

Let's proceed to step 5:
91 can be fit into 579 6 times, resulting in a remainder of 33.
The next digit of our result is 6. 
Result so far: 976.0
The remainder is 33 after subtracting 546 from 579.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 91

Advancing to step 6:
331 divided by 91 is 3 with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 9763.0
The remainder is 58 after subtracting 273 from 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
If we divide 580 by 91, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 9763.6
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 91 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 9763.63
If we take 273 away from 340, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
When dividing 670 by 91, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 9763.637
Subtract 637 from 670 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
91 can be fit into 330 3 times, resulting in a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 9763.6373
The remainder is 57 after subtracting 273 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
91 goes into 570 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 9763.63736
If we take 546 away from 570, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
91 can be fit into 240 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 9763.637362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
If we divide 580 by 91, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 9763.6373626
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
91 can be fit into 340 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 9763.63736263
If we subtract 273 from 340, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

In conclusion, the division gives 9763.63736263 with a balance of 6.7e-08.
