We look at the division of 552069 by 65 
The aim is to understand the frequency of 65 in 552069.

Step 1:
65 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 65

Step 2:
65 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 65

Step 3:
552 divided by 65 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 32 after subtracting 520 from 552.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 65

Advancing to step 4:
320 divided by 65 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 260 from 320, we get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 65

Moving on to step 5:
606 divided by 65 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
Deduct 585 from 606 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 65

Step 6:
65 goes into 219 3 times with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 8493.0
Subtracting 195 from 219 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
65 can be fit into 240 3 times, resulting in a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 8493.3
The remainder is 45 after subtracting 195 from 240.
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 8:
If we divide 450 by 65, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 8493.36
Deduct 390 from 450 and we're left 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.

Going ahead to step 9:
If we divide 600 by 65, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8493.369
The remainder is 15 after subtracting 585 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 65 fits into 150 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8493.3692
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.

Let's proceed to step 11:
65 can be fit into 200 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 8493.36923
If we take 195 away from 200, we end up 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 12:
65 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8493.36923
If we take 0 away from 50, we end up 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.

Going ahead to step 13:
If we divide 500 by 65, we get 7 and a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 8493.3692307
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.

Moving on to step 14:
65 goes into 450 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 8493.36923076
Deduct 390 from 450 and we're left 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.

The final outcome is 8493.36923076, with a leftover of 6e-08.
