We're dividing 637271 by 66 
The aim is to understand the frequency of 66 in 637271.

Moving on to step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 66

Advancing to step 2:
66 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 66

Going ahead to step 3:
637 divided by 66 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 594 from 637 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 66

Going ahead to step 4:
66 goes into 432 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 396 from 432 to get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 66

Advancing to step 5:
66 can be fit into 367 5 times, resulting in a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
The remainder is 37 after subtracting 330 from 367.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 66

Moving on to step 6:
371 divided by 66 is 5 with a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 9655.0
Subtracting 330 from 371 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
410 divided by 66 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 9655.6
If we take 396 away from 410, we end up 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.

Moving on to step 8:
If we divide 140 by 66, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 9655.62
Deduct 132 from 140 and we're left 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.

Step 9:
If we divide 80 by 66, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 9655.621
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.

Advancing to step 10:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 9655.6212
If we take 132 away from 140, we end up 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 11:
If we divide 80 by 66, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 9655.62121
Subtract 66 from 80 to 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.

Step 12:
If we divide 140 by 66, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 9655.621212
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.

Let's proceed to step 13:
80 divided by 66 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 9655.6212121
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.

On to step 14:
The number 66 fits into 140 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9655.62121212
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 quotient of the division is 9655.62121212, and the remainder is 8e-09.
