732331 divided by 91 
The aim is to understand the frequency of 91 in 732331.

Let's proceed to step 1:
The number 91 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 91

Let's proceed to step 2:
73 divided by 91 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 91

Step 3:
When dividing 732 by 91, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 728 from 732 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 91

Advancing to step 4:
The number 91 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtract 0 from 43 to get 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 91

Advancing to step 5:
If we divide 433 by 91, we get 4 and a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 804.0
If we subtract 364 from 433, we get 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 91

Step 6:
91 goes into 691 7 times with a remainder of 54.
The next digit of our result is 7. 
Result so far: 8047.0
If we take 637 away from 691, we end up 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.

On to step 7:
The number 91 fits into 540 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 8047.5
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 8:
The number 91 fits into 850 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 8047.59
Subtract 819 from 850 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 9:
310 divided by 91 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 8047.593
Subtracting 273 from 310 leaves us 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.

On to step 10:
If we divide 370 by 91, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 8047.5934
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.

Let's proceed to step 11:
91 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8047.5934
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
91 goes into 600 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 8047.593406
If we take 546 away from 600, we end up 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 13:
540 divided by 91 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 8047.5934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
When dividing 850 by 91, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 8047.59340659
The remainder is 31 after subtracting 819 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 8047.59340659 and a remainder of 3.1e-08.
