We're dividing 320747 by 91 
The aim is to understand the frequency of 91 in 320747.

Let's proceed to step 1:
3 divided by 91 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 91

Step 2:
91 goes into 32 0 times with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 91

Step 3:
91 goes into 320 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 273 from 320 and we're left with 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 91

Let's proceed to step 4:
91 can be fit into 477 5 times, resulting in a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 455 from 477, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 91

Moving on to step 5:
If we divide 224 by 91, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 352.0
The remainder is 42 after subtracting 182 from 224.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 91

Step 6:
91 goes into 427 4 times with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 3524.0
If we take 364 away from 427, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
The number 91 fits into 630 6 times, leaving a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 3524.6
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 8:
When dividing 840 by 91, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 3524.69
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
When dividing 210 by 91, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 3524.692
Deduct 182 from 210 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
280 divided by 91 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3524.6923
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
The number 91 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3524.6923
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
If we divide 700 by 91, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 3524.692307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 13:
91 goes into 630 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 3524.6923076
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
If we divide 840 by 91, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 3524.69230769
Subtract 819 from 840 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 3524.69230769, and the remainder is 2.1e-08.
