We're dividing 220805 by 91 
The aim is to understand the frequency of 91 in 220805.

Advancing to step 1:
91 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 91

Going ahead to step 2:
When dividing 22 by 91, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 91

Advancing to step 3:
91 can be fit into 220 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 182 from 220 leaves us with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 91

Moving on to step 4:
The number 91 fits into 388 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 364 from 388 leaves us with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 91

On to step 5:
When dividing 240 by 91, we get 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 242.0
The remainder is 58 after subtracting 182 from 240.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 91

On to step 6:
When dividing 585 by 91, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 2426.0
If we take 546 away from 585, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 91 fits into 390 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 2426.4
Subtract 364 from 390 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 2426.42
If we subtract 182 from 260, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
91 can be fit into 780 8 times, resulting in a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 2426.428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
91 goes into 520 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 2426.4285
Deduct 455 from 520 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
91 can be fit into 650 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2426.42857
If we take 637 away from 650, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
130 divided by 91 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 2426.428571
Deduct 91 from 130 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
91 goes into 390 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2426.4285714
If we subtract 364 from 390, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
If we divide 260 by 91, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 2426.42857142
If we subtract 182 from 260, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 2426.42857142 with a balance of 7.8e-08.
