4557 divided by 12 
Let's see how many times 12 fits into 4557.

On to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Let's proceed to step 2:
45 divided by 12 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 36 from 45.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Step 3:
When dividing 95 by 12, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 84 from 95 leaves us with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 12

On to step 4:
When dividing 117 by 12, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 379.0
Deduct 108 from 117 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 5:
90 divided by 12 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 379.7
Subtracting 84 from 90 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 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 379.75
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 7:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 379.75
Subtract 0 from 0 to 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.

Advancing to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 379.75
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.

After the division, we end up with 379.75 and a remainder of 0.0.
