We look at the division of 831978 by 65 
The aim is to understand the frequency of 65 in 831978.

Step 1:
If we divide 8 by 65, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 65

Going ahead to step 2:
When dividing 83 by 65, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 65 from 83, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 65

Advancing to step 3:
The number 65 fits into 181 2 times, leaving a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 130 from 181 to get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 65

Let's proceed to step 4:
If we divide 519 by 65, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 64 after subtracting 455 from 519.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 65

Moving on to step 5:
647 divided by 65 is 9 with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
The remainder is 62 after subtracting 585 from 647.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 65

Let's proceed to step 6:
The number 65 fits into 628 9 times, leaving a remainder of 43.
The next digit of our result is 9. 
Result so far: 12799.0
If we take 585 away from 628, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
65 goes into 430 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 12799.6
If we take 390 away from 430, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
65 goes into 400 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 12799.66
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 12799.66 with a balance of 0.01.
