We're dividing 449527 by 91 
The aim is to understand the frequency of 91 in 449527.

On to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 91

On to step 2:
The number 91 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 91

Advancing to step 3:
449 divided by 91 is 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 364 from 449, we get 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 91

Advancing to step 4:
When dividing 855 by 91, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 819 from 855 to get 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 91

Step 5:
The number 91 fits into 362 3 times, leaving a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 493.0
The remainder is 89 after subtracting 273 from 362.
Grab the next digit (7) from the dividend, add it to 89, then carry on: 897 / 91

Advancing to step 6:
91 can be fit into 897 9 times, resulting in a remainder of 78.
The next digit of our result is 9. 
Result so far: 4939.0
If we subtract 819 from 897, 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 7:
91 can be fit into 780 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 4939.8
If we take 728 away from 780, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
If we divide 520 by 91, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 4939.85
Subtract 455 from 520 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
650 divided by 91 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4939.857
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 4939.8571
If we take 91 away from 130, 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.

Going ahead to step 11:
91 can be fit into 390 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4939.85714
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.

Advancing to step 12:
91 goes into 260 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 4939.857142
Deduct 182 from 260 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
780 divided by 91 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 4939.8571428
If we subtract 728 from 780, we get 52.
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 14:
The number 91 fits into 520 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 4939.85714285
If we take 455 away from 520, we end up 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.

In conclusion, the division gives 4939.85714285 with a balance of 6.5e-08.
