208972 divided by 12 
The aim is to understand the frequency of 12 in 208972.

Step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

Advancing to step 2:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 8 after subtracting 12 from 20.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 12

Step 3:
12 goes into 88 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 84 from 88 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 12

Going ahead to step 4:
12 goes into 49 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 174.0
The remainder is 1 after subtracting 48 from 49.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Step 5:
When dividing 17 by 12, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1741.0
Deduct 12 from 17 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Going ahead to step 6:
12 can be fit into 52 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 17414.0
Deduct 48 from 52 and we're left 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.

Moving on to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 17414.3
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.

On to step 8:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 17414.33
Subtracting 36 from 40 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.

The final result is 17414.33 with a remainder of 0.004.
