We look at the division of 256307 by 65 
The aim is to understand the frequency of 65 in 256307.

Advancing to step 1:
65 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 65

Moving on to step 2:
65 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 65

Advancing to step 3:
When dividing 256 by 65, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 195 away from 256, we end up with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 65

Advancing to step 4:
The number 65 fits into 613 9 times, leaving a remainder of 28.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 28 after subtracting 585 from 613.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 65

Advancing to step 5:
If we divide 280 by 65, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 394.0
Subtract 260 from 280 to get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 65

Moving on to step 6:
When dividing 207 by 65, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3943.0
If we take 195 away from 207, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 65 fits into 120 1 times, leaving a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 3943.1
If we subtract 65 from 120, we 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 8:
The number 65 fits into 550 8 times, leaving a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 3943.18
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 65 fits into 300 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 3943.184
Subtracting 260 from 300 leaves us 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.

Step 10:
The number 65 fits into 400 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 3943.1846
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.

Moving on to step 11:
65 goes into 100 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 3943.18461
Deduct 65 from 100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
The number 65 fits into 350 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3943.184615
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.

Advancing to step 13:
65 goes into 250 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 3943.1846153
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.

Moving on to step 14:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 3943.18461538
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 3943.18461538 and a remainder of 3e-08.
