We look at the division of 422400 by 12 
Our goal is to divide 422400 by 12.

Advancing to step 1:
12 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

On to step 2:
12 goes into 42 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 36 from 42 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

Let's proceed to step 3:
12 can be fit into 62 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 60 from 62 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Let's proceed to step 4:
12 goes into 24 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 352.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 12

Moving on to step 5:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3520.0
Subtract 0 from 0 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 12

Moving on to step 6:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35200.0
Subtract 0 from 0 to 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.

Let's proceed to step 7:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35200.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35200.0
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.

In conclusion, the division gives 35200.0 with a balance of 0.0.
