215316 divided by 12 
Our goal is to divide 215316 by 12.

Let's proceed to step 1:
12 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Going ahead to step 2:
When dividing 21 by 12, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 12 away from 21, we end up with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 12

Advancing to step 3:
95 divided by 12 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 84 from 95 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 12

On to step 4:
12 can be fit into 113 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 179.0
Subtract 108 from 113 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 12

Step 5:
The number 12 fits into 51 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 1794.0
If we take 48 away from 51, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

Let's proceed to step 6:
If we divide 36 by 12, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 17943.0
Subtract 36 from 36 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.

Moving on to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17943.0
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.

Step 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17943.0
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.

In conclusion, the division gives 17943.0 with a balance of 0.0.
