We look at the division of 53295889 by 65 
The aim is to understand the frequency of 65 in 53295889.

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
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 65

On to step 2:
The number 65 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 65

Let's proceed to step 3:
532 divided by 65 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 520 from 532 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 65

Advancing to step 4:
The number 65 fits into 129 1 times, leaving a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 64 after subtracting 65 from 129.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 65

Let's proceed to step 5:
When dividing 645 by 65, we get 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 819.0
Deduct 585 from 645 and we're left with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 65

Advancing to step 6:
608 divided by 65 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 8199.0
Subtract 585 from 608 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 65

Let's proceed to step 7:
When dividing 238 by 65, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 81993.0
Subtract 195 from 238 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 65

Step 8:
The number 65 fits into 439 6 times, leaving a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 819936.0
Subtracting 390 from 439 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
When dividing 490 by 65, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 819936.7
Deduct 455 from 490 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.

On to step 10:
When dividing 350 by 65, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 819936.75
If we subtract 325 from 350, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
250 divided by 65 is 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 819936.753
If we subtract 195 from 250, 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.

Advancing to step 12:
If we divide 550 by 65, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 819936.7538
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 819936.75384
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 14:
The number 65 fits into 400 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 819936.753846
The remainder is 10 after subtracting 390 from 400.
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 15:
When dividing 100 by 65, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 819936.7538461
If we subtract 65 from 100, we 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.

On to step 16:
If we divide 350 by 65, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 819936.75384615
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.

The final outcome is 819936.75384615, with a leftover of 2.5e-08.
