We're dividing 568306 by 91 
The aim is to understand the frequency of 91 in 568306.

Step 1:
When dividing 5 by 91, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 91

Let's proceed to step 2:
When dividing 56 by 91, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 91

Moving on to step 3:
If we divide 568 by 91, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 546 from 568 to get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 91

Advancing to step 4:
If we divide 223 by 91, we get 2 and a remainder of 41.
The next digit of our result is 2. 
Result so far: 62.0
If we subtract 182 from 223, we get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 91

On to step 5:
When dividing 410 by 91, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 624.0
The remainder is 46 after subtracting 364 from 410.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 91

Step 6:
The number 91 fits into 466 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 6245.0
Deduct 455 from 466 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 91 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 6245.1
The remainder is 19 after subtracting 91 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
When dividing 190 by 91, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6245.12
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 91 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6245.12
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
91 can be fit into 800 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 6245.1208
If we subtract 728 from 800, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
The number 91 fits into 720 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 6245.12087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
91 can be fit into 830 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 6245.120879
If we take 819 away from 830, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
When dividing 110 by 91, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 6245.1208791
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
When dividing 190 by 91, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 6245.12087912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 6245.12087912 with a remaining 8e-09.
