We're dividing 66699290 by 565 
The aim is to understand the frequency of 565 in 66699290.

Let's proceed to step 1:
The number 565 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 565

Going ahead to step 2:
When dividing 66 by 565, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 565

On to step 3:
565 can be fit into 666 1 times, resulting in a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 565 from 666 leaves us with 101.
Include the next digit (9) from the dividend after 101, then repeat: 1019 / 565

On to step 4:
1019 divided by 565 is 1 with a remainder of 454.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 565 from 1019 to get 454.
Grab the next digit (9) from the dividend, add it to 454, then carry on: 4549 / 565

Advancing to step 5:
565 can be fit into 4549 8 times, resulting in a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
The remainder is 29 after subtracting 4520 from 4549.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 565

On to step 6:
565 can be fit into 292 0 times, resulting in a remainder of 292.
Record the quotient 0 as the next digit in the result. 
Result so far: 1180.0
Subtract 0 from 292 to get 292.
Bring next digit (9) of the dividend behind the 292 and repeat the process: 2929 / 565

Let's proceed to step 7:
2929 divided by 565 is 5 with a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 11805.0
Subtract 2825 from 2929 to get 104.
Append the next digit (0) from the dividend to 104 and continue with: 1040 / 565

On to step 8:
565 goes into 1040 1 times with a remainder of 475.
The number 1 becomes the next digit in our result. 
Result so far: 118051.0
Subtracting 565 from 1040 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 9:
If we divide 4750 by 565, we get 8 and a remainder of 230.
Write down 8 as next digit of the result. 
Result so far: 118051.8
Subtract 4520 from 4750 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
When dividing 2300 by 565, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 118051.84
The remainder is 40 after subtracting 2260 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
565 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 118051.84
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
565 goes into 4000 7 times with a remainder of 45.
The next digit of our result is 7. 
Result so far: 118051.8407
Deduct 3955 from 4000 and we're left 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 13:
If we divide 450 by 565, we get 0 and a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 118051.8407
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 14:
565 goes into 4500 7 times with a remainder of 545.
The number 7 becomes the next digit in our result. 
Result so far: 118051.840707
The remainder is 545 after subtracting 3955 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 15:
565 goes into 5450 9 times with a remainder of 365.
Write down 9 as next digit of the result. 
Result so far: 118051.8407079
The remainder is 365 after subtracting 5085 from 5450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 16:
When dividing 3650 by 565, we get 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 118051.84070796
If we subtract 3390 from 3650, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 118051.84070796 with a balance of 2.6e-07.
