We're dividing 30780 by 12 
We want to divide 30780 by 12.

Moving on to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 12

Step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 24 from 30 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Step 3:
If we divide 67 by 12, we get 5 and a remainder of 7.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 60 from 67 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

On to step 4:
12 goes into 78 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
If we take 72 away from 78, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 12

Going ahead to step 5:
If we divide 60 by 12, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2565.0
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.

Moving on to step 6:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2565.0
Subtracting 0 from 0 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.

Let's proceed to step 7:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2565.0
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.

Our division results in 2565.0 with a remaining 0.0.
