We divide 473390 by 12
Let's see how many times 12 fits into 473390.

Advancing to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 12

Moving on to step 2:
If we divide 47 by 12, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 36 away from 47, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

On to step 3:
12 can be fit into 113 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 108 from 113, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Going ahead to step 4:
When dividing 53 by 12, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Deduct 48 from 53 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 12

Going ahead to step 5:
59 divided by 12 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 3944.0
Subtract 48 from 59 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 12

On to step 6:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 39449.0
The remainder is 2 after subtracting 108 from 110.
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 7:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 39449.1
Deduct 12 from 20 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.

On to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 39449.16
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.

Let's proceed to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 39449.166
Subtracting 72 from 80 leaves us 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.

After the division, we end up with 39449.166 and a remainder of 0.0008.
