We look at the division of 628566 by 65 
The aim is to understand the frequency of 65 in 628566.

Step 1:
65 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 65

Going ahead to step 2:
65 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 65

Step 3:
When dividing 628 by 65, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 585 from 628 and we're left with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 65

Moving on to step 4:
435 divided by 65 is 6 with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 45 after subtracting 390 from 435.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 65

Going ahead to step 5:
When dividing 456 by 65, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 967.0
Subtracting 455 from 456 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 65

Going ahead to step 6:
65 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 9670.0
Deduct 0 from 16 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 65 fits into 160 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 9670.2
If we subtract 130 from 160, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 65, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 9670.24
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
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: 9670.246
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 65 fits into 100 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 9670.2461
If we subtract 65 from 100, we 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 11:
If we divide 350 by 65, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 9670.24615
If we subtract 325 from 350, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The next digit of our result is 3. 
Result so far: 9670.246153
Subtract 195 from 250 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
550 divided by 65 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 9670.2461538
The remainder is 30 after subtracting 520 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 9670.24615384
If we subtract 260 from 300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 9670.24615384 with a balance of 4e-08.
