We divide 245248 by 12
Let's see how many times 12 fits into 245248.

On to step 1:
12 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

Advancing to step 2:
When dividing 24 by 12, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 24 from 24 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 12

Going ahead to step 3:
If we divide 5 by 12, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 12

On to step 4:
When dividing 52 by 12, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 204.0
The remainder is 4 after subtracting 48 from 52.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 12

On to step 5:
44 divided by 12 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 2043.0
The remainder is 8 after subtracting 36 from 44.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 12

Going ahead to step 6:
88 divided by 12 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 20437.0
Subtract 84 from 88 to 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.

Step 7:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 20437.3
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.

Advancing to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 20437.33
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.

The final result is 20437.33 with a remainder of 0.004.
