We're dividing 154992 by 66 
The aim is to understand the frequency of 66 in 154992.

Step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 66

Moving on to step 2:
The number 66 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 66

Going ahead to step 3:
When dividing 154 by 66, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 22 after subtracting 132 from 154.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 66

Moving on to step 4:
66 goes into 229 3 times with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 198 from 229 leaves us with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 66

Let's proceed to step 5:
66 can be fit into 319 4 times, resulting in a remainder of 55.
The next digit of our result is 4. 
Result so far: 234.0
Subtracting 264 from 319 leaves us with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 66

On to step 6:
552 divided by 66 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 2348.0
If we subtract 528 from 552, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 66, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 2348.3
Deduct 198 from 240 and we're left 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.

Step 8:
420 divided by 66 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2348.36
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.

On to step 9:
When dividing 240 by 66, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 2348.363
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.

Going ahead to step 10:
If we divide 420 by 66, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2348.3636
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.

Moving on to step 11:
When dividing 240 by 66, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 2348.36363
If we take 198 away from 240, we end up 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.

Step 12:
When dividing 420 by 66, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 2348.363636
Subtract 396 from 420 to get 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 13:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 2348.3636363
If we take 198 away from 240, we end up 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.

Advancing to step 14:
420 divided by 66 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2348.36363636
Deduct 396 from 420 and we're left 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.

In conclusion, the division gives 2348.36363636 with a balance of 2.4e-08.
