We look at the division of 814291 by 65 
The aim is to understand the frequency of 65 in 814291.

Let's proceed to step 1:
When dividing 8 by 65, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 65

Step 2:
81 divided by 65 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 65 from 81 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 65

Advancing to step 3:
65 can be fit into 164 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 130 from 164 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 65

Going ahead to step 4:
The number 65 fits into 342 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 125.0
The remainder is 17 after subtracting 325 from 342.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 65

On to step 5:
When dividing 179 by 65, we get 2 with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 1252.0
If we take 130 away from 179, we end up with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 65

Moving on to step 6:
If we divide 491 by 65, we get 7 and a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 12527.0
Subtract 455 from 491 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
65 can be fit into 360 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 12527.5
Subtract 325 from 360 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
350 divided by 65 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12527.55
If we take 325 away from 350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 12527.55, with a leftover of 0.025.
