383982 divided by 66 
The aim is to understand the frequency of 66 in 383982.

Let's proceed to step 1:
66 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 66

Step 2:
66 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 66

Let's proceed to step 3:
66 goes into 383 5 times with a remainder of 53.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 330 from 383, we get 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 66

Advancing to step 4:
If we divide 539 by 66, we get 8 and a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 528 from 539 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 66

On to step 5:
When dividing 118 by 66, we get 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 581.0
Deduct 66 from 118 and we're left with 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 66

On to step 6:
66 can be fit into 522 7 times, resulting in a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 5817.0
Deduct 462 from 522 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5817.9
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5817.9
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5817.909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 66 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 5817.909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5817.90909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
60 divided by 66 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5817.90909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
600 divided by 66 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5817.9090909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
66 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5817.9090909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 5817.9090909 and a remainder of 6e-08.
