Let's divide 69564096 by 66
The aim is to understand the frequency of 66 in 69564096.

Advancing to step 1:
66 can be fit into 6 0 times, resulting in 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.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 66

Advancing to step 2:
If we divide 69 by 66, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 66 from 69 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 66

Step 3:
66 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 35, we end up with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 66

Advancing to step 4:
If we divide 356 by 66, we get 5 and a remainder of 26.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 330 from 356 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 66

Advancing to step 5:
If we divide 264 by 66, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 1054.0
If we take 264 away from 264, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 66

Let's proceed to step 6:
The number 66 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10540.0
If we subtract 0 from 0, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 66

On to step 7:
When dividing 9 by 66, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 105400.0
If we subtract 0 from 9, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 66

Advancing to step 8:
The number 66 fits into 96 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1054001.0
If we take 66 away from 96, 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.

Going ahead to step 9:
If we divide 300 by 66, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1054001.4
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 66, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1054001.45
Subtract 330 from 360 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.

On to step 11:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1054001.454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1054001.4545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
66 goes into 300 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1054001.45454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1054001.454545
Deduct 330 from 360 and we're left 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.

On to step 15:
If we divide 300 by 66, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 1054001.4545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
360 divided by 66 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1054001.45454545
If we take 330 away from 360, 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.

In conclusion, the division gives 1054001.45454545 with a balance of 3e-08.
