We divide 356744 by 91
The aim is to understand the frequency of 91 in 356744.

Step 1:
3 divided by 91 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 91

Step 2:
The number 91 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 91

Step 3:
91 goes into 356 3 times with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 273 from 356 leaves us with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 91

On to step 4:
The number 91 fits into 837 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 819 from 837 to get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 91

Advancing to step 5:
The number 91 fits into 184 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 392.0
If we take 182 away from 184, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 91

Advancing to step 6:
24 divided by 91 is 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 3920.0
Subtracting 0 from 24 leaves us 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:
The number 91 fits into 240 2 times, leaving a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 3920.2
Deduct 182 from 240 and we're left 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.

Moving on to step 8:
If we divide 580 by 91, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 3920.26
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.

Moving on to step 9:
When dividing 340 by 91, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3920.263
Deduct 273 from 340 and we're left 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 can be fit into 670 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 3920.2637
Subtract 637 from 670 to get 33.
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:
If we divide 330 by 91, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 3920.26373
Subtract 273 from 330 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
570 divided by 91 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 3920.263736
Subtract 546 from 570 to get 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 13:
The number 91 fits into 240 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 3920.2637362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
When dividing 580 by 91, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 3920.26373626
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.

Our division results in 3920.26373626 with a remaining 3.4e-08.
