Let's divide 478993 by 12
We want to divide 478993 by 12.

Going ahead 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
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 12

Let's proceed to step 2:
47 divided by 12 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 36 from 47, we get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 12

Let's proceed to step 3:
118 divided by 12 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 108 from 118 and we're left with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 12

Moving on to step 4:
The number 12 fits into 109 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
The remainder is 1 after subtracting 108 from 109.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 12

Advancing to step 5:
When dividing 19 by 12, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 3991.0
If we take 12 away from 19, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Moving on to step 6:
When dividing 73 by 12, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 39916.0
Subtract 72 from 73 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39916.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
12 goes into 100 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 39916.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 39916.083
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 39916.0833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 39916.0833 with a remainder of 4e-05.
