We look at the division of 472391 by 12 
Let's see how many times 12 fits into 472391.

On to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 12

On to step 2:
If we divide 47 by 12, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 36 from 47 leaves us with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 12

Step 3:
The number 12 fits into 112 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 108 away from 112, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Let's proceed to step 4:
If we divide 43 by 12, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Subtract 36 from 43 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

Let's proceed to step 5:
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: 3936.0
Deduct 72 from 79 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

Let's proceed to step 6:
The number 12 fits into 71 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 39365.0
Subtract 60 from 71 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 12, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 39365.9
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 39365.91
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 39365.916
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 39365.9166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 39365.9166 and a remainder of 8e-05.
