782162 ÷ 91 
The aim is to understand the frequency of 91 in 782162.

Advancing to step 1:
When dividing 7 by 91, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 91

Let's proceed to step 2:
When dividing 78 by 91, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 91

Let's proceed to step 3:
91 goes into 782 8 times with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 728 from 782 to get 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 91

Step 4:
91 can be fit into 541 5 times, resulting in a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 455 from 541, we get 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 91

Going ahead to step 5:
866 divided by 91 is 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 859.0
Subtract 819 from 866 to get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 91

Advancing to step 6:
91 goes into 472 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 8595.0
Subtracting 455 from 472 leaves us 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.

Let's proceed to step 7:
If we divide 170 by 91, we get 1 and a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 8595.1
Deduct 91 from 170 and we're left 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.

Going ahead to step 8:
91 can be fit into 790 8 times, resulting in a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 8595.18
If we take 728 away from 790, we end up 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.

Advancing to step 9:
620 divided by 91 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 8595.186
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.

Step 10:
91 goes into 740 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8595.1868
If we take 728 away from 740, we end up with 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 11:
91 can be fit into 120 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 8595.18681
Subtract 91 from 120 to 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.

Step 12:
The number 91 fits into 290 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 8595.186813
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.

Moving on to step 13:
170 divided by 91 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 8595.1868131
Deduct 91 from 170 and we're left 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.

Moving on to step 14:
If we divide 790 by 91, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 8595.18681318
If we take 728 away from 790, we end up 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.

In conclusion, the division gives 8595.18681318 with a balance of 6.2e-08.
