We look at the division of 662995 by 12 
The aim is to understand the frequency of 12 in 662995.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 12

Advancing to step 2:
66 divided by 12 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 60 from 66, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 12

Going ahead to step 3:
The number 12 fits into 62 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we take 60 away from 62, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 12

Advancing to step 4:
The number 12 fits into 29 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 552.0
If we subtract 24 from 29, we get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 12

Step 5:
When dividing 59 by 12, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 5524.0
If we take 48 away from 59, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

Step 6:
If we divide 115 by 12, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 55249.0
Subtracting 108 from 115 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 12 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 55249.5
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 55249.58
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 55249.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 55249.5833
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 55249.5833 with a remaining 4e-05.
