827318 ÷ 66 
The aim is to understand the frequency of 66 in 827318.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 66

Going ahead to step 2:
66 goes into 82 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 16 after subtracting 66 from 82.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 66

Advancing to step 3:
66 can be fit into 167 2 times, resulting in a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 132 from 167 to get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 66

Moving on to step 4:
If we divide 353 by 66, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we subtract 330 from 353, we get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 66

Moving on to step 5:
231 divided by 66 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1253.0
If we take 198 away from 231, we end up with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 66

Moving on to step 6:
66 can be fit into 338 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 12535.0
Deduct 330 from 338 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.

Going ahead to step 7:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 12535.1
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.

Let's proceed to step 8:
When dividing 140 by 66, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12535.12
If we subtract 132 from 140, we 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.

Advancing to step 9:
When dividing 80 by 66, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 12535.121
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.

Going ahead to step 10:
When dividing 140 by 66, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12535.1212
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.

Going ahead to step 11:
The number 66 fits into 80 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 12535.12121
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 12:
66 can be fit into 140 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 12535.121212
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 13:
80 divided by 66 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 12535.1212121
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 14:
When dividing 140 by 66, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12535.12121212
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.

Our division results in 12535.12121212 with a remaining 8e-09.
