504666 ÷ 12 
Let's see how many times 12 fits into 504666.

Going ahead to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Let's proceed to step 2:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 50, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

Moving on to step 3:
12 can be fit into 24 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 24 from 24 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 12

Let's proceed to step 4:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Moving on to step 5:
The number 12 fits into 66 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 4205.0
If we subtract 60 from 66, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Let's proceed to step 6:
When dividing 66 by 12, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 42055.0
Deduct 60 from 66 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 42055.5
The remainder is 0 after subtracting 60 from 60.
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.
Use 0 as the next digit of our solution. 
Result so far: 42055.5
Subtracting 0 from 0 leaves us 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.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42055.5
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 42055.5 and a remainder of 0.0.
