Let's divide 555629 by 66
The aim is to understand the frequency of 66 in 555629.

Going ahead to step 1:
5 divided by 66 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 66

Going ahead to step 2:
If we divide 55 by 66, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (5) from the dividend to 55 and continue with: 555 / 66

Advancing to step 3:
66 can be fit into 555 8 times, resulting in a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 528 from 555 leaves us with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 66

Step 4:
When dividing 276 by 66, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we take 264 away from 276, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 66

Let's proceed to step 5:
If we divide 122 by 66, we get 1 and a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 841.0
If we take 66 away from 122, we end up with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 66

Advancing to step 6:
569 divided by 66 is 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 8418.0
Subtract 528 from 569 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
If we divide 410 by 66, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 8418.6
Subtracting 396 from 410 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 66, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 8418.62
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 8418.621
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
When dividing 140 by 66, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8418.6212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
80 divided by 66 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 8418.62121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
If we divide 140 by 66, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8418.621212
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
66 goes into 80 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 8418.6212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8418.62121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 8418.62121212 with a remainder of 8e-09.
