Let's divide 426004 by 12
The aim is to understand the frequency of 12 in 426004.

Advancing to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 2:
12 can be fit into 42 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 36 from 42, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Moving on to step 3:
12 goes into 66 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 60 from 66, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

Moving on to step 4:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 355.0
If we subtract 60 from 60, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 12

On to step 5:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3550.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 12

Going ahead to step 6:
4 divided by 12 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 35500.0
If we subtract 0 from 4, 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.

Advancing to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 35500.3
If we take 36 away from 40, 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.

Moving on to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 35500.33
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.

The final result is 35500.33 with a remainder of 0.004.
