552847 divided by 66 
The aim is to understand the frequency of 66 in 552847.

On to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 66

On to step 2:
The number 66 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 66

Going ahead to step 3:
If we divide 552 by 66, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 528 from 552 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 66

Moving on to step 4:
When dividing 248 by 66, we get 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 198 from 248 leaves us with 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 66

Moving on to step 5:
66 goes into 504 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 837.0
The remainder is 42 after subtracting 462 from 504.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 66

On to step 6:
When dividing 427 by 66, we get 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 8376.0
Deduct 396 from 427 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
When dividing 310 by 66, we get 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 8376.4
If we take 264 away from 310, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 8376.46
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 8376.469
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8376.4696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 8376.46969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 8376.469696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
66 goes into 640 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 8376.4696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 8376.46969696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.
