We divide 478511 by 12
Let's see how many times 12 fits into 478511.

On to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 12

Let's proceed 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
Deduct 36 from 47 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Step 3:
12 goes into 118 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 108 from 118 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 12

Moving on to step 4:
When dividing 105 by 12, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 398.0
Deduct 96 from 105 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

On to step 5:
When dividing 91 by 12, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 3987.0
If we subtract 84 from 91, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

Step 6:
When dividing 71 by 12, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 39875.0
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.

On to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 39875.9
Subtracting 108 from 110 leaves us 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.

Step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 39875.91
Subtracting 12 from 20 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.

Advancing to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 39875.916
If we subtract 72 from 80, we get 8.
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 10:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 39875.9166
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 39875.9166 and a remainder of 8e-05.
