We're dividing 302645 by 65 
The aim is to understand the frequency of 65 in 302645.

Step 1:
If we divide 3 by 65, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 65

Step 2:
When dividing 30 by 65, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 65

Going ahead to step 3:
If we divide 302 by 65, we get 4 and a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 260 away from 302, we end up with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 65

Going ahead to step 4:
If we divide 426 by 65, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 36 after subtracting 390 from 426.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 65

Moving on to step 5:
If we divide 364 by 65, we get 5 and a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 465.0
Subtracting 325 from 364 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 65

Let's proceed to step 6:
65 goes into 395 6 times with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 4656.0
The remainder is 5 after subtracting 390 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4656.0
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.

Step 8:
500 divided by 65 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 4656.07
Subtract 455 from 500 to 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.

On to step 9:
450 divided by 65 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4656.076
Deduct 390 from 450 and we're left 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.

Step 10:
65 can be fit into 600 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 4656.0769
If we subtract 585 from 600, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
If we divide 150 by 65, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 4656.07692
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
65 can be fit into 200 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4656.076923
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.

Advancing to step 13:
If we divide 50 by 65, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4656.076923
If we subtract 0 from 50, we get 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 14:
65 goes into 500 7 times with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 4656.07692307
If we subtract 455 from 500, 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.

The quotient of the division is 4656.07692307, and the remainder is 4.5e-08.
