We look at the division of 122724 by 91 
The aim is to understand the frequency of 91 in 122724.

Let's proceed to step 1:
When dividing 1 by 91, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 91

Moving on to step 2:
The number 91 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 91

On to step 3:
122 divided by 91 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 91 from 122, we get 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 91

Step 4:
If we divide 317 by 91, we get 3 and a remainder of 44.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 273 from 317, we get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 91

Advancing to step 5:
When dividing 442 by 91, we get 4 with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we take 364 away from 442, we end up with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 91

Step 6:
91 goes into 784 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 1348.0
Deduct 728 from 784 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1348.6
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 91 fits into 140 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 1348.61
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
91 goes into 490 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1348.615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
If we divide 350 by 91, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 1348.6153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 11:
The number 91 fits into 770 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 1348.61538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
420 divided by 91 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1348.615384
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
91 goes into 560 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1348.6153846
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
When dividing 140 by 91, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1348.61538461
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 1348.61538461 with a balance of 4.9e-08.
