202029 divided by 12 
The aim is to understand the frequency of 12 in 202029.

On to step 1:
2 divided by 12 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Let's proceed to step 2:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 12

Going ahead to step 3:
12 goes into 82 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 72 from 82 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 12

Moving on to step 4:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 168.0
Subtract 96 from 100 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

On to step 5:
If we divide 42 by 12, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 1683.0
Subtracting 36 from 42 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 12

Let's proceed to step 6:
When dividing 69 by 12, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 16835.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 16835.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16835.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16835.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16835.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 16835.75 with a remaining 0.0.
