We divide 622815 by 91
The aim is to understand the frequency of 91 in 622815.

Advancing to step 1:
When dividing 6 by 91, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 91

On to step 2:
When dividing 62 by 91, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 91

Advancing to step 3:
If we divide 622 by 91, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 546 from 622, we get 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 91

Going ahead to step 4:
91 can be fit into 768 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 728 from 768, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 91

Moving on to step 5:
When dividing 401 by 91, we get 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 684.0
Subtract 364 from 401 to get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 91

Step 6:
The number 91 fits into 375 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 6844.0
The remainder is 11 after subtracting 364 from 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 91, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 6844.1
Deduct 91 from 110 and we're left 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.

Moving on 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: 6844.12
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 91, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 6844.12
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.

Moving on to step 10:
800 divided by 91 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 6844.1208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
720 divided by 91 is 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 6844.12087
Subtracting 637 from 720 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 6844.120879
Subtracting 819 from 830 leaves us 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.

Let's proceed to step 13:
The number 91 fits into 110 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 6844.1208791
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.

Moving on to step 14:
91 can be fit into 190 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6844.12087912
Subtracting 182 from 190 leaves us with 8.
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 6844.12087912 with a remaining 8e-09.
