We're dividing 654660 by 12 
Our goal is to divide 654660 by 12.

Step 1:
12 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 12

Step 2:
65 divided by 12 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 12

Moving on to step 3:
The number 12 fits into 54 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtract 48 from 54 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 12

Going ahead to step 4:
66 divided by 12 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 545.0
Subtract 60 from 66 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Let's proceed to step 5:
12 can be fit into 66 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5455.0
If we subtract 60 from 66, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Let's proceed to step 6:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 54555.0
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.

Let's proceed to step 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54555.0
If we take 0 away from 0, 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.

Advancing to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 54555.0
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 54555.0 and a remainder of 0.0.
