We're dividing 45147055 by 66 
The aim is to understand the frequency of 66 in 45147055.

Moving on to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 66

Advancing to step 2:
If we divide 45 by 66, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 66

On to step 3:
If we divide 451 by 66, we get 6 and a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 396 from 451 and we're left with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 66

Advancing to step 4:
66 can be fit into 554 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 26 after subtracting 528 from 554.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 66

Going ahead to step 5:
66 goes into 267 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 684.0
The remainder is 3 after subtracting 264 from 267.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 66

Advancing to step 6:
66 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6840.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 66

Moving on to step 7:
66 goes into 305 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 68404.0
If we take 264 away from 305, we end up with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 66

Moving on to step 8:
66 can be fit into 415 6 times, resulting in a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 684046.0
The remainder is 19 after subtracting 396 from 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 66 is 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 684046.2
The remainder is 58 after subtracting 132 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
When dividing 580 by 66, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 684046.28
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
520 divided by 66 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 684046.287
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
66 goes into 580 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 684046.2878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 684046.28787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 684046.287878
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
If we divide 520 by 66, we get 7 and a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 684046.2878787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 16:
66 goes into 580 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 684046.28787878
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 684046.28787878 with a remainder of 5.2e-08.
