We look at the division of 18724 by 66 
The aim is to understand the frequency of 66 in 18724.

Moving on to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 66

Let's proceed to step 2:
66 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 66

Step 3:
The number 66 fits into 187 2 times, leaving a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 132 from 187 and we're left with 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 66

Step 4:
66 can be fit into 552 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 528 from 552 to get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 66

Moving on to step 5:
66 goes into 244 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 283.0
Subtract 198 from 244 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 6:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 283.6
If we take 396 away from 460, we end up 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.

Going ahead to step 7:
66 goes into 640 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 283.69
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 283.696
The remainder is 64 after subtracting 396 from 460.
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 9:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 283.6969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
66 goes into 460 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 283.69696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 283.696969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
66 goes into 460 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 283.6969696
If we take 396 away from 460, we end up 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.

Step 13:
640 divided by 66 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 283.69696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 283.69696969 with a remaining 4.6e-08.
