We divide 439047 by 12
Let's see how many times 12 fits into 439047.

Going ahead to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 12

Advancing to step 2:
The number 12 fits into 43 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 7 after subtracting 36 from 43.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Step 3:
12 can be fit into 79 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 72 from 79 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 12

Let's proceed to step 4:
When dividing 70 by 12, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 365.0
Subtract 60 from 70 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 12

Let's proceed to step 5:
The number 12 fits into 104 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3658.0
If we subtract 96 from 104, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

On to step 6:
When dividing 87 by 12, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 36587.0
Subtracting 84 from 87 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 36587.2
Subtract 24 from 30 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.

Going ahead to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 36587.25
If we subtract 60 from 60, 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.

Let's proceed to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36587.25
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.

Let's proceed to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 36587.25
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.

After the division, we end up with 36587.25 and a remainder of 0.0.
