Let's divide 459203 by 12
We want to divide 459203 by 12.

On to step 1:
12 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

Going ahead to step 2:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 9 after subtracting 36 from 45.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Let's proceed to step 3:
If we divide 99 by 12, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 3 after subtracting 96 from 99.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 12

Moving on to step 4:
If we divide 32 by 12, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
If we take 24 away from 32, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Moving on to step 5:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 3826.0
The remainder is 8 after subtracting 72 from 80.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 12

On to step 6:
12 can be fit into 83 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 38266.0
Subtracting 72 from 83 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 12 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 38266.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 38266.91
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 38266.916
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 38266.9166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 38266.9166 with a balance of 8e-05.
