Let's divide 484449 by 12
We're looking to find how many times 12 goes into 484449.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 12

Let's proceed to step 2:
When dividing 48 by 12, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 48, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 12

Step 3:
4 divided by 12 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 12

Let's proceed to step 4:
12 goes into 44 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 403.0
If we subtract 36 from 44, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

Advancing to step 5:
84 divided by 12 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 4037.0
If we take 84 away from 84, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Going ahead to step 6:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 40370.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 40370.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40370.75
If we take 60 away from 60, 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.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40370.75
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 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40370.75
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 40370.75 with a balance of 0.0.
