447490 ÷ 12 
Let's see how many times 12 fits into 447490.

Let's proceed to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 12

Step 2:
When dividing 44 by 12, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 36 from 44 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

On to step 3:
12 goes into 87 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 84 from 87 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

On to step 4:
If we divide 34 by 12, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 372.0
The remainder is 10 after subtracting 24 from 34.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

Let's proceed to step 5:
If we divide 109 by 12, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 3729.0
Deduct 108 from 109 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Let's proceed to step 6:
12 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 37290.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 12 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 37290.8
If we take 96 away from 100, we end up 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.

Step 8:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 37290.83
If we subtract 36 from 40, we 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 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 37290.833
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.

Our division results in 37290.833 with a remaining 0.0004.
