We look at the division of 30936 by 12 
We're looking to find how many times 12 goes into 30936.

Let's proceed to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 12

Going ahead to step 2:
12 goes into 30 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 24 away from 30, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Step 3:
69 divided by 12 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 60 from 69 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 12

Let's proceed to step 4:
12 goes into 93 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 257.0
If we subtract 84 from 93, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 12

On to step 5:
96 divided by 12 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 2578.0
The remainder is 0 after subtracting 96 from 96.
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 6:
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: 2578.0
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.

Step 7:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2578.0
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.

The final result is 2578.0 with a remainder of 0.0.
