We're dividing 75242536 by 65 
The aim is to understand the frequency of 65 in 75242536.

Advancing to step 1:
The number 65 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 65

Moving on to step 2:
75 divided by 65 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 65 from 75.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 65

Moving on to step 3:
When dividing 102 by 65, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 65 from 102, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 65

On to step 4:
When dividing 374 by 65, we get 5 with a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Deduct 325 from 374 and we're left with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 65

Moving on to step 5:
If we divide 492 by 65, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 1157.0
Deduct 455 from 492 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 65

Advancing to step 6:
The number 65 fits into 375 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 11575.0
If we subtract 325 from 375, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 65

Going ahead to step 7:
When dividing 503 by 65, we get 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 115757.0
If we subtract 455 from 503, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 65

Let's proceed to step 8:
The number 65 fits into 486 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 1157577.0
Subtracting 455 from 486 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
65 can be fit into 310 4 times, resulting in a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 1157577.4
The remainder is 50 after subtracting 260 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 65 fits into 500 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 1157577.47
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
450 divided by 65 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 1157577.476
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.

Advancing to step 12:
If we divide 600 by 65, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1157577.4769
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
65 goes into 150 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1157577.47692
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.

Advancing to step 14:
65 goes into 200 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1157577.476923
Subtracting 195 from 200 leaves us with 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 15:
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: 1157577.476923
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.

On to step 16:
65 goes into 500 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 1157577.47692307
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 1157577.47692307 and a remainder of 4.5e-08.
