We look at the division of 560429 by 65 
The aim is to understand the frequency of 65 in 560429.

Advancing to 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.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 65

Going ahead to step 2:
If we divide 56 by 65, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 65

Going ahead to step 3:
When dividing 560 by 65, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 520 from 560 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 65

Let's proceed to step 4:
When dividing 404 by 65, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we subtract 390 from 404, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 65

Advancing to step 5:
65 goes into 142 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
Subtracting 130 from 142 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 65

Moving on to step 6:
If we divide 129 by 65, we get 1 and a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 8621.0
Subtracting 65 from 129 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
The number 65 fits into 640 9 times, leaving a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 8621.9
Deduct 585 from 640 and we're left 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.

Going ahead to step 8:
550 divided by 65 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 8621.98
If we subtract 520 from 550, we 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.

Going ahead to step 9:
If we divide 300 by 65, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8621.984
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.

Advancing to step 10:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 8621.9846
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.

Advancing to step 11:
When dividing 100 by 65, we get 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 8621.98461
Subtracting 65 from 100 leaves us 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.

Let's proceed to step 12:
65 goes into 350 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8621.984615
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.

On to step 13:
65 goes into 250 3 times with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 8621.9846153
Deduct 195 from 250 and we're left 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.

Moving on to step 14:
65 goes into 550 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8621.98461538
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.

The final outcome is 8621.98461538, with a leftover of 3e-08.
