We divide 335359 by 91
The aim is to understand the frequency of 91 in 335359.

On to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 91

On to step 2:
91 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 91

Step 3:
91 goes into 335 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 273 from 335 leaves us with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 91

Going ahead to step 4:
91 goes into 623 6 times with a remainder of 77.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 77 after subtracting 546 from 623.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 91

Step 5:
When dividing 775 by 91, we get 8 with a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 368.0
If we subtract 728 from 775, we get 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 91

Advancing to step 6:
The number 91 fits into 479 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 3685.0
Deduct 455 from 479 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
91 can be fit into 240 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 3685.2
Subtracting 182 from 240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
When dividing 580 by 91, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 3685.26
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
If we divide 340 by 91, we get 3 and a remainder of 67.
The next digit of our result is 3. 
Result so far: 3685.263
If we take 273 away from 340, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
91 goes into 670 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 3685.2637
The remainder is 33 after subtracting 637 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
The number 91 fits into 330 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 3685.26373
The remainder is 57 after subtracting 273 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
When dividing 570 by 91, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 3685.263736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 91 is 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 3685.2637362
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
91 goes into 580 6 times with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 3685.26373626
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 3685.26373626 with a balance of 3.4e-08.
