Let's divide 511980 by 12
Our goal is to divide 511980 by 12.

Going ahead to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 12

Advancing to step 2:
If we divide 51 by 12, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 48 from 51.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Advancing to step 3:
When dividing 31 by 12, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 24 from 31, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Going ahead to step 4:
79 divided by 12 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 426.0
Subtract 72 from 79 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Step 5:
12 goes into 78 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4266.0
Subtracting 72 from 78 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Step 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 42665.0
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42665.0
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.

On to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42665.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 42665.0 with a balance of 0.0.
