Let's divide 566888 by 66
The aim is to understand the frequency of 66 in 566888.

On to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 66

On to step 2:
The number 66 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 66

Going ahead to step 3:
If we divide 566 by 66, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 528 from 566 leaves us with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 66

On to step 4:
388 divided by 66 is 5 with a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 330 from 388, we get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 66

Step 5:
The number 66 fits into 588 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 858.0
If we take 528 away from 588, we end up with 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 66

Going ahead to step 6:
66 can be fit into 608 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 8589.0
If we subtract 594 from 608, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
If we divide 140 by 66, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8589.2
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 8589.21
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
66 goes into 140 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8589.212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 66, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 8589.2121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 66, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8589.21212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 66, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 8589.212121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
66 can be fit into 140 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8589.2121212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
If we divide 80 by 66, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 8589.21212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 8589.21212121 with a balance of 1.4e-08.
