222744 ÷ 66 
The aim is to understand the frequency of 66 in 222744.

Advancing to step 1:
2 divided by 66 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 66

Going ahead to step 2:
22 divided by 66 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 66

Step 3:
222 divided by 66 is 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 198 from 222 to get 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 66

Moving on to step 4:
The number 66 fits into 247 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 198 from 247, we get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 66

Step 5:
If we divide 494 by 66, we get 7 and a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 337.0
The remainder is 32 after subtracting 462 from 494.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 66

Step 6:
66 can be fit into 324 4 times, resulting in a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 3374.0
Deduct 264 from 324 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.

Step 7:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3374.9
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.

On to step 8:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 3374.9
If we subtract 0 from 60, we 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.

Advancing to step 9:
When dividing 600 by 66, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3374.909
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 10:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3374.909
If we subtract 0 from 60, we 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 11:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 3374.90909
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 12:
60 divided by 66 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 3374.90909
If we take 0 away from 60, we end up 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.

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: 3374.9090909
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.

Let's proceed to step 14:
When dividing 60 by 66, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3374.9090909
Deduct 0 from 60 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.

After the division, we end up with 3374.9090909 and a remainder of 6e-08.
