820792 divided by 91 
The aim is to understand the frequency of 91 in 820792.

Let's proceed to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 91

Moving on to step 2:
82 divided by 91 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 91

Step 3:
91 goes into 820 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 819 from 820 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 91

Advancing to step 4:
If we divide 17 by 91, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 17 to get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 91

Advancing to step 5:
179 divided by 91 is 1 with a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 901.0
Subtract 91 from 179 to get 88.
Grab the next digit (2) from the dividend, add it to 88, then carry on: 882 / 91

Going ahead to step 6:
882 divided by 91 is 9 with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 9019.0
Subtract 819 from 882 to get 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 7:
If we divide 630 by 91, we get 6 and a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 9019.6
If we subtract 546 from 630, we get 84.
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:
91 can be fit into 840 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 9019.69
Deduct 819 from 840 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
210 divided by 91 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 9019.692
Subtract 182 from 210 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 91, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9019.6923
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
91 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 9019.6923
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
When dividing 700 by 91, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 9019.692307
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:
630 divided by 91 is 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 9019.6923076
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.

Going ahead to step 14:
When dividing 840 by 91, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9019.69230769
Subtracting 819 from 840 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 9019.69230769 with a remaining 2.1e-08.
