We divide 511456 by 12
We're looking to find how many times 12 goes into 511456.

Advancing to step 1:
12 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 12

Moving on 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.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 12

Let's proceed to step 3:
12 goes into 31 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 24 from 31 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

Advancing to step 4:
When dividing 74 by 12, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 426.0
The remainder is 2 after subtracting 72 from 74.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 12

Going ahead to step 5:
12 can be fit into 25 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 4262.0
Subtracting 24 from 25 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 12

Going ahead to step 6:
The number 12 fits into 16 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 42621.0
Subtract 12 from 16 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 42621.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 42621.33
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.

In conclusion, the division gives 42621.33 with a balance of 0.004.
