We look at the division of 99565695 by 689 
The aim is to understand the frequency of 689 in 99565695.

Step 1:
689 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 689

Let's proceed to step 2:
If we divide 99 by 689, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (5) from the dividend, attach it to 99 and continue: 995 / 689

On to step 3:
689 can be fit into 995 1 times, resulting in a remainder of 306.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 689 from 995, we get 306.
Include the next digit (6) from the dividend after 306, then repeat: 3066 / 689

Advancing to step 4:
689 can be fit into 3066 4 times, resulting in a remainder of 310.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 310 after subtracting 2756 from 3066.
Include the next digit (5) from the dividend after 310, then repeat: 3105 / 689

Step 5:
689 can be fit into 3105 4 times, resulting in a remainder of 349.
Put 4 as the next digit of the answer. 
Result so far: 144.0
The remainder is 349 after subtracting 2756 from 3105.
Grab the next digit (6) from the dividend, add it to 349, then carry on: 3496 / 689

On to step 6:
3496 divided by 689 is 5 with a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 1445.0
If we take 3445 away from 3496, we end up with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 689

Moving on to step 7:
If we divide 519 by 689, we get 0 and a remainder of 519.
Record the quotient 0 as the next digit in the result. 
Result so far: 14450.0
If we subtract 0 from 519, we get 519.
Include the next digit (5) from the dividend after 519, then repeat: 5195 / 689

Step 8:
The number 689 fits into 5195 7 times, leaving a remainder of 372.
Write down 7 as next digit of the result. 
Result so far: 144507.0
Subtract 4823 from 5195 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 9:
The number 689 fits into 3720 5 times, leaving a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 144507.5
If we subtract 3445 from 3720, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
2750 divided by 689 is 3 with a remainder of 683.
The number 3 becomes the next digit in our result. 
Result so far: 144507.53
If we subtract 2067 from 2750, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 11:
When dividing 6830 by 689, we get 9 with a remainder of 629.
The next digit of our result is 9. 
Result so far: 144507.539
Deduct 6201 from 6830 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Advancing to step 12:
689 can be fit into 6290 9 times, resulting in a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 144507.5399
Subtract 6201 from 6290 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Our division results in 144507.5399 with a remaining 0.00089.
