558786 divided by 12 
Our goal is to divide 558786 by 12.

Moving on to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

On to step 2:
When dividing 55 by 12, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

On to step 3:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 72 from 78, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Going ahead to step 4:
When dividing 67 by 12, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 465.0
If we take 60 away from 67, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Advancing to step 5:
If we divide 78 by 12, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4656.0
Deduct 72 from 78 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

Step 6:
66 divided by 12 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 46565.0
Subtract 60 from 66 to 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.

Let's proceed to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 46565.5
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.

Advancing to step 8:
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: 46565.5
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.

Moving on to step 9:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 46565.5
The remainder is 0 after subtracting 0 from 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 46565.5 with a remainder of 0.0.
