We divide 486876 by 12
Our goal is to divide 486876 by 12.

Moving on to step 1:
12 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Advancing to step 2:
48 divided by 12 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 0 after subtracting 48 from 48.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 12

Moving on to step 3:
6 divided by 12 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

Let's proceed to step 4:
If we divide 68 by 12, we get 5 and a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtract 60 from 68 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

Advancing to step 5:
12 can be fit into 87 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4057.0
The remainder is 3 after subtracting 84 from 87.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 12

Moving on to step 6:
If we divide 36 by 12, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 40573.0
If we take 36 away from 36, we end up 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 7:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40573.0
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.

Going ahead to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40573.0
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.

The final result is 40573.0 with a remainder of 0.0.
