Let's divide 458428 by 12
Our goal is to divide 458428 by 12.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Step 2:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 36 from 45 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Let's proceed to step 3:
If we divide 98 by 12, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 96 from 98 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Moving on to step 4:
24 divided by 12 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 382.0
The remainder is 0 after subtracting 24 from 24.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 12

On to step 5:
2 divided by 12 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 3820.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Step 6:
28 divided by 12 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 38202.0
Subtract 24 from 28 to 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.

Let's proceed 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: 38202.3
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.

Going ahead to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 38202.33
Subtract 36 from 40 to 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.

In conclusion, the division gives 38202.33 with a balance of 0.004.
