30057 ÷ 12 
We're looking to find how many times 12 goes into 30057.

Advancing to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 24 from 30, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 12

Advancing to step 3:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 60 away from 60, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 12

Going ahead to step 4:
When dividing 5 by 12, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 12

On to step 5:
When dividing 57 by 12, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 2504.0
The remainder is 9 after subtracting 48 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2504.7
If we take 84 away from 90, we end up 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.

Moving on to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2504.75
If we subtract 60 from 60, 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:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2504.75
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.

Going ahead to step 9:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2504.75
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 2504.75 with a remainder of 0.0.
