Let's divide 250243 by 12
We want to divide 250243 by 12.

Moving on to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 12

Going ahead to step 2:
12 goes into 25 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Advancing to step 3:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Let's proceed to step 4:
The number 12 fits into 102 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
Subtracting 96 from 102 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 12

Going ahead to step 5:
When dividing 64 by 12, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 2085.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 12

Step 6:
12 goes into 43 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 20853.0
Subtracting 36 from 43 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 20853.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20853.58
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 20853.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 20853.5833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 20853.5833, with a leftover of 4e-05.
