We're dividing 297783 by 91 
The aim is to understand the frequency of 91 in 297783.

Let's proceed to step 1:
If we divide 2 by 91, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 91

On to step 2:
29 divided by 91 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 91

Step 3:
297 divided by 91 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 273 from 297 to get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 91

Let's proceed to step 4:
91 goes into 247 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 182 from 247, we get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 91

Going ahead to step 5:
If we divide 658 by 91, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
If we subtract 637 from 658, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 91

Going ahead to step 6:
If we divide 213 by 91, we get 2 and a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 3272.0
Subtract 182 from 213 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 91 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 3272.3
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
The number 91 fits into 370 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 3272.34
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 91, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3272.34
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 91, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 3272.3406
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
The number 91 fits into 540 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 3272.34065
Subtract 455 from 540 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
91 goes into 850 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 3272.340659
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
When dividing 310 by 91, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 3272.3406593
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
The number 91 fits into 370 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3272.34065934
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 3272.34065934 with a balance of 6e-09.
