We divide 398244 by 12
Our goal is to divide 398244 by 12.

On to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Let's proceed to step 2:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

Advancing to step 3:
The number 12 fits into 38 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 36 away from 38, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 12

On to step 4:
12 can be fit into 22 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 331.0
Subtracting 12 from 22 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 12

Moving on to step 5:
12 goes into 104 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3318.0
Subtract 96 from 104 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

Let's proceed to step 6:
12 can be fit into 84 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 33187.0
If we take 84 away from 84, 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 7:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33187.0
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.

Moving on to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33187.0
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 33187.0, and the remainder is 0.0.
