We're dividing 75506317 by 65 
The aim is to understand the frequency of 65 in 75506317.

On to step 1:
7 divided by 65 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 65

Step 2:
The number 65 fits into 75 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 65 from 75, we get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 65

On to step 3:
The number 65 fits into 105 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 65 away from 105, we end up with 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 65

On to step 4:
When dividing 400 by 65, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 116.0
The remainder is 10 after subtracting 390 from 400.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 65

Step 5:
If we divide 106 by 65, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 1161.0
If we take 65 away from 106, we end up with 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 65

Advancing to step 6:
65 can be fit into 413 6 times, resulting in a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 11616.0
The remainder is 23 after subtracting 390 from 413.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 65

Moving on to step 7:
65 can be fit into 231 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 116163.0
Deduct 195 from 231 and we're left with 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 65

Let's proceed to step 8:
65 can be fit into 367 5 times, resulting in a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 1161635.0
The remainder is 42 after subtracting 325 from 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
420 divided by 65 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 1161635.6
The remainder is 30 after subtracting 390 from 420.
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 10:
300 divided by 65 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 1161635.64
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.

Let's proceed to step 11:
When dividing 400 by 65, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1161635.646
If we subtract 390 from 400, 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.

Let's proceed to step 12:
If we divide 100 by 65, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1161635.6461
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.

Moving on to step 13:
The number 65 fits into 350 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 1161635.64615
Subtracting 325 from 350 leaves us 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 14:
The number 65 fits into 250 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 1161635.646153
Subtracting 195 from 250 leaves us 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.

On to step 15:
65 goes into 550 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1161635.6461538
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.

Advancing to step 16:
300 divided by 65 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 1161635.64615384
The remainder is 40 after subtracting 260 from 300.
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 1161635.64615384 with a balance of 4e-08.
