43227041 ÷ 91 
The aim is to understand the frequency of 91 in 43227041.

Advancing to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 91

Advancing to step 2:
If we divide 43 by 91, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 91

Step 3:
If we divide 432 by 91, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 364 from 432 leaves us with 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 91

Advancing to step 4:
91 can be fit into 682 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 637 from 682 leaves us with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 91

Step 5:
91 can be fit into 457 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 475.0
The remainder is 2 after subtracting 455 from 457.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 91

Moving on to step 6:
The number 91 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4750.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 91

On to step 7:
If we divide 204 by 91, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 47502.0
Deduct 182 from 204 and we're left with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 91

Step 8:
If we divide 221 by 91, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 475022.0
If we subtract 182 from 221, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
The number 91 fits into 390 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 475022.4
If we take 364 away from 390, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 91 fits into 260 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 475022.42
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.

Going ahead to step 11:
If we divide 780 by 91, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 475022.428
Deduct 728 from 780 and we're left 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.

Let's proceed to step 12:
91 goes into 520 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 475022.4285
If we subtract 455 from 520, we 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 13:
91 can be fit into 650 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 475022.42857
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.

Advancing to step 14:
130 divided by 91 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 475022.428571
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.

Let's proceed to step 15:
390 divided by 91 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 475022.4285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
If we divide 260 by 91, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 475022.42857142
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.

The final result is 475022.42857142 with a remainder of 7.8e-08.
