577752 ÷ 12 
We want to figure out the number of times 577752 can be divided by 12.

On to step 1:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 12

Let's proceed to step 2:
57 divided by 12 is 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 48 from 57 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Let's proceed to step 3:
12 goes into 97 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 96 from 97 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Step 4:
If we divide 17 by 12, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
Deduct 12 from 17 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

Let's proceed to step 5:
The number 12 fits into 55 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 4814.0
If we subtract 48 from 55, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 12

Going ahead to step 6:
If we divide 72 by 12, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 48146.0
If we take 72 away from 72, 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.

Step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48146.0
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.

On to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48146.0
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.

The final outcome is 48146.0, with a leftover of 0.0.
