We look at the division of 814773 by 65 
The aim is to understand the frequency of 65 in 814773.

On to step 1:
When dividing 8 by 65, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
65 can be fit into 81 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 65 away from 81, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 65

Advancing to step 3:
The number 65 fits into 164 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 130 away from 164, we end up with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 65

Let's proceed to step 4:
65 can be fit into 347 5 times, resulting in a remainder of 22.
The next digit of our result is 5. 
Result so far: 125.0
Deduct 325 from 347 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 65

Moving on to step 5:
227 divided by 65 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 1253.0
Subtracting 195 from 227 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 65

Let's proceed to step 6:
323 divided by 65 is 4 with a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 12534.0
The remainder is 63 after subtracting 260 from 323.
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 65, we get 9 and a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 12534.9
If we subtract 585 from 630, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 65, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 12534.96
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
65 can be fit into 600 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 12534.969
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 65 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12534.9692
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 65, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12534.96923
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
65 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12534.96923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
The number 65 fits into 500 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 12534.9692307
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
If we divide 450 by 65, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 12534.96923076
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 12534.96923076 with a remainder of 6e-08.
