We're dividing 577122 by 12 
We're looking to find how many times 12 goes into 577122.

Going ahead to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 12

Moving on to step 2:
12 goes into 57 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 9 after subtracting 48 from 57.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 12

Let's proceed to step 3:
12 can be fit into 97 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 96 from 97 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 12

Moving on to step 4:
When dividing 11 by 12, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we subtract 0 from 11, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 12

Advancing to step 5:
If we divide 112 by 12, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 4809.0
The remainder is 4 after subtracting 108 from 112.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Going ahead to step 6:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 48093.0
Subtracting 36 from 42 leaves us with 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:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 48093.5
Subtracting 60 from 60 leaves us 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 8:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48093.5
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.

Let's proceed to step 9:
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: 48093.5
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.

Our division results in 48093.5 with a remaining 0.0.
