We're dividing 447369 by 12 
We want to divide 447369 by 12.

Let's proceed to step 1:
12 goes into 4 0 times with 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.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 12

On to step 2:
12 can be fit into 44 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 36 from 44 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Let's proceed to step 3:
If we divide 87 by 12, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 84 from 87 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Going ahead to step 4:
12 can be fit into 33 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 372.0
If we subtract 24 from 33, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 12

Going ahead to step 5:
96 divided by 12 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 3728.0
The remainder is 0 after subtracting 96 from 96.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 12

Going ahead to step 6:
12 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 37280.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 37280.7
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 37280.75
The remainder is 0 after subtracting 60 from 60.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 37280.75
The remainder is 0 after subtracting 0 from 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 10:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37280.75
Deduct 0 from 0 and we're left 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.

After the division, we end up with 37280.75 and a remainder of 0.0.
