We're dividing 892173 by 66 
The aim is to understand the frequency of 66 in 892173.

Advancing to step 1:
66 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 66

On to step 2:
When dividing 89 by 66, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 66 from 89, we get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 66

Step 3:
66 goes into 232 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 34 after subtracting 198 from 232.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 66

Step 4:
The number 66 fits into 341 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 135.0
Subtract 330 from 341 to get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 66

Going ahead to step 5:
66 goes into 117 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1351.0
Subtracting 66 from 117 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 66

Step 6:
66 goes into 513 7 times with a remainder of 51.
The next digit of our result is 7. 
Result so far: 13517.0
Subtracting 462 from 513 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
66 can be fit into 510 7 times, resulting in a remainder of 48.
The next digit of our result is 7. 
Result so far: 13517.7
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
If we divide 480 by 66, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 13517.77
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 13517.77, and the remainder is 0.018.
