We look at the division of 154622 by 66 
The aim is to understand the frequency of 66 in 154622.

Moving on to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 66

Going ahead to step 2:
66 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 66

Advancing to step 3:
66 can be fit into 154 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 132 from 154 and we're left with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 66

On to step 4:
If we divide 226 by 66, we get 3 and a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 198 from 226, we get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 66

Moving on to step 5:
If we divide 282 by 66, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we subtract 264 from 282, we get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 66

Let's proceed to step 6:
66 goes into 182 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 2342.0
If we take 132 away from 182, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2342.7
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 2342.75
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 2342.757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
If we divide 380 by 66, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2342.7575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
66 goes into 500 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2342.75757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
66 goes into 380 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2342.757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 2342.7575757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
380 divided by 66 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2342.75757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 2342.75757575 with a remaining 5e-08.
