We're dividing 327583 by 91 
The aim is to understand the frequency of 91 in 327583.

Step 1:
91 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 91

On to step 2:
The number 91 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 91

Going ahead to step 3:
91 goes into 327 3 times with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 273 from 327 leaves us with 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 91

Let's proceed to step 4:
91 goes into 545 5 times with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 455 from 545 leaves us with 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 91

Going ahead to step 5:
The number 91 fits into 908 9 times, leaving a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 359.0
Deduct 819 from 908 and we're left with 89.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 91

Going ahead to step 6:
If we divide 893 by 91, we get 9 and a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 3599.0
If we take 819 away from 893, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
If we divide 740 by 91, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3599.8
Subtract 728 from 740 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 91, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 3599.81
If we subtract 91 from 120, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
When dividing 290 by 91, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3599.813
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
When dividing 170 by 91, we get 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 3599.8131
Subtracting 91 from 170 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
91 goes into 790 8 times with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3599.81318
Deduct 728 from 790 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
91 can be fit into 620 6 times, resulting in a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 3599.813186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
91 goes into 740 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3599.8131868
If we subtract 728 from 740, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 91 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 3599.81318681
Deduct 91 from 120 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 3599.81318681 with a remaining 2.9e-08.
