We divide 250902 by 12
We're looking to find how many times 12 goes into 250902.

Going ahead to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Step 2:
12 can be fit into 25 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 25, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Moving on to step 3:
12 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Let's proceed to step 4:
12 can be fit into 109 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 209.0
If we take 108 away from 109, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

Moving on to step 5:
12 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2090.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 12

Step 6:
12 goes into 102 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 20908.0
If we take 96 away from 102, 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:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20908.5
If we take 60 away from 60, 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.

Let's proceed to step 8:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20908.5
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.

Advancing to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20908.5
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.

In conclusion, the division gives 20908.5 with a balance of 0.0.
