We look at the division of 363222 by 66 
The aim is to understand the frequency of 66 in 363222.

Step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 66

On to step 2:
66 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 66

Let's proceed to step 3:
66 goes into 363 5 times with a remainder of 33.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 330 from 363 to get 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 66

Advancing to step 4:
When dividing 332 by 66, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 55.0
If we subtract 330 from 332, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 66

Advancing to step 5:
66 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 550.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 66

Let's proceed to step 6:
222 divided by 66 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 5503.0
Subtracting 198 from 222 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
If we divide 240 by 66, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 5503.3
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5503.36
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 5503.363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
When dividing 420 by 66, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5503.3636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 5503.36363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 5503.363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 5503.3636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5503.36363636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 5503.36363636 with a remaining 2.4e-08.
