We look at the division of 154740 by 66 
The aim is to understand the frequency of 66 in 154740.

Going ahead to step 1:
66 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 66

Advancing to step 2:
When dividing 15 by 66, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 66

Moving on to step 3:
If we divide 154 by 66, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 132 from 154, we get 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 66

Advancing to step 4:
If we divide 227 by 66, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 198 away from 227, we end up with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 66

Moving on to step 5:
If we divide 294 by 66, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Subtracting 264 from 294 leaves us with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 66

Advancing to step 6:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2344.0
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 66, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2344.5
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 2344.54
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 2344.545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 66, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 2344.5454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2344.54545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 66 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 2344.545454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
66 goes into 360 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 2344.5454545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 66 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2344.54545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 2344.54545454, with a leftover of 3.6e-08.
