Let's divide 495672 by 91
The aim is to understand the frequency of 91 in 495672.

Advancing to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 91

On to step 2:
91 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 91

Going ahead to step 3:
If we divide 495 by 91, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 40 after subtracting 455 from 495.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 91

Moving on to step 4:
When dividing 406 by 91, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 364 from 406 leaves us with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 91

Moving on to step 5:
91 can be fit into 427 4 times, resulting in a remainder of 63.
The next digit of our result is 4. 
Result so far: 544.0
If we subtract 364 from 427, we get 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 91

Step 6:
91 goes into 632 6 times with a remainder of 86.
The next digit of our result is 6. 
Result so far: 5446.0
If we take 546 away from 632, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 7:
91 goes into 860 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 5446.9
Deduct 819 from 860 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
410 divided by 91 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 5446.94
Subtract 364 from 410 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
If we divide 460 by 91, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5446.945
Deduct 455 from 460 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 91 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5446.945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 91, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 5446.94505
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
When dividing 450 by 91, we get 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 5446.945054
Deduct 364 from 450 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 13:
The number 91 fits into 860 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 5446.9450549
Deduct 819 from 860 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
When dividing 410 by 91, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 5446.94505494
Subtracting 364 from 410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 5446.94505494 and a remainder of 4.6e-08.
