We look at the division of 513385 by 65 
The aim is to understand the frequency of 65 in 513385.

Step 1:
65 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 65

Let's proceed to step 2:
65 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 65

Moving on to step 3:
65 can be fit into 513 7 times, resulting in a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 455 from 513, we get 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 65

Going ahead to step 4:
65 goes into 583 8 times with a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 520 from 583 leaves us with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 65

Going ahead to step 5:
65 goes into 638 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
The remainder is 53 after subtracting 585 from 638.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 65

Let's proceed to step 6:
65 can be fit into 535 8 times, resulting in a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 7898.0
If we subtract 520 from 535, 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.

Let's proceed to step 7:
If we divide 150 by 65, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 7898.2
If we subtract 130 from 150, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 65, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 7898.23
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.

Let's proceed to step 9:
50 divided by 65 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 7898.23
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 65, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 7898.2307
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 11:
450 divided by 65 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 7898.23076
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.

On to step 12:
When dividing 600 by 65, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 7898.230769
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.

Advancing to step 13:
65 can be fit into 150 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 7898.2307692
If we take 130 away from 150, we end up 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.

On to step 14:
When dividing 200 by 65, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 7898.23076923
If we subtract 195 from 200, we 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.

The final outcome is 7898.23076923, with a leftover of 5e-09.
