We're dividing 515893 by 65 
The aim is to understand the frequency of 65 in 515893.

Step 1:
65 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 65

Step 2:
If we divide 51 by 65, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 65

Advancing to step 3:
515 divided by 65 is 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 455 from 515 leaves us with 60.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 65

Let's proceed to step 4:
When dividing 608 by 65, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Deduct 585 from 608 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 65

Let's proceed to step 5:
65 goes into 239 3 times with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 793.0
If we take 195 away from 239, we end up with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 65

On to step 6:
If we divide 443 by 65, we get 6 and a remainder of 53.
The next digit of our result is 6. 
Result so far: 7936.0
Deduct 390 from 443 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
The number 65 fits into 530 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 7936.8
If we subtract 520 from 530, we 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.

Going ahead to step 8:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 7936.81
The remainder is 35 after subtracting 65 from 100.
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 9:
65 goes into 350 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7936.815
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.

Going ahead to step 10:
65 can be fit into 250 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 7936.8153
If we take 195 away from 250, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
If we divide 550 by 65, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 7936.81538
If we take 520 away from 550, we end up 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 12:
65 can be fit into 300 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 7936.815384
Deduct 260 from 300 and we're left 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.

Moving on to step 13:
If we divide 400 by 65, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 7936.8153846
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.

Going ahead to step 14:
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: 7936.81538461
Subtract 65 from 100 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.

In conclusion, the division gives 7936.81538461 with a balance of 3.5e-08.
