We're dividing 426904 by 12 
We want to divide 426904 by 12.

Step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 2:
When dividing 42 by 12, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 36 from 42 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Going ahead to step 3:
The number 12 fits into 66 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 60 from 66 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 12

Step 4:
12 goes into 69 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 355.0
If we subtract 60 from 69, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Let's proceed to step 5:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 3557.0
If we take 84 away from 90, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

Step 6:
12 can be fit into 64 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 35575.0
The remainder is 4 after subtracting 60 from 64.
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:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 35575.3
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.

Advancing to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 35575.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 35575.33 and a remainder of 0.004.
