We look at the division of 206269 by 12 
The aim is to understand the frequency of 12 in 206269.

Step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Moving on to step 2:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 12

Let's proceed to step 3:
12 goes into 86 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 84 from 86 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 12

Moving on to step 4:
12 goes into 22 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 12 from 22 leaves us with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

On to step 5:
When dividing 106 by 12, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 1718.0
If we take 96 away from 106, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

Let's proceed to step 6:
12 goes into 109 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 17189.0
Subtract 108 from 109 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 17189.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 17189.08
If we take 96 away from 100, we end up 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.

Step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 17189.083
Deduct 36 from 40 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.

Advancing to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 17189.0833
Deduct 36 from 40 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.

Our division results in 17189.0833 with a remaining 4e-05.
