Let's divide 257203 by 12
We want to figure out the number of times 257203 can be divided by 12.

On to step 1:
12 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 12

Step 2:
25 divided by 12 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 24 away from 25, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Going ahead to step 3:
The number 12 fits into 17 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 5 after subtracting 12 from 17.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

Step 4:
When dividing 52 by 12, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtracting 48 from 52 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

Let's proceed to step 5:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 2143.0
Subtract 36 from 40 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Going ahead to step 6:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 21433.0
The remainder is 7 after subtracting 36 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
12 goes into 70 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 21433.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 21433.58
Subtracting 96 from 100 leaves us 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 21433.583
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 21433.5833
Subtract 36 from 40 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.

In conclusion, the division gives 21433.5833 with a balance of 4e-05.
