579510 ÷ 12 
We want to divide 579510 by 12.

Step 1:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Moving on to step 2:
12 can be fit into 57 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 48 from 57 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 12

Step 3:
When dividing 99 by 12, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 48.0
If we take 96 away from 99, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Let's proceed to step 4:
When dividing 35 by 12, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 482.0
The remainder is 11 after subtracting 24 from 35.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 12

On to step 5:
12 can be fit into 111 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 4829.0
If we subtract 108 from 111, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

On to step 6:
When dividing 30 by 12, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 48292.0
If we subtract 24 from 30, we get 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.
Use 5 as the next digit of our solution. 
Result so far: 48292.5
Deduct 60 from 60 and we're left 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 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48292.5
Deduct 0 from 0 and we're left 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 9:
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: 48292.5
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.

The final result is 48292.5 with a remainder of 0.0.
