We divide 403013 by 12
Let's see how many times 12 fits into 403013.

On to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 12

Advancing to step 2:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 36 from 40 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

Advancing to step 3:
The number 12 fits into 43 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 36 from 43 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Advancing to step 4:
70 divided by 12 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 335.0
If we subtract 60 from 70, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 12

Let's proceed to step 5:
12 can be fit into 101 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 3358.0
Deduct 96 from 101 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 12

On to step 6:
The number 12 fits into 53 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 33584.0
Subtract 48 from 53 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
12 goes into 50 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 33584.4
Subtracting 48 from 50 leaves us 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.

Advancing to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 33584.41
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 33584.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 33584.4166
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.

In conclusion, the division gives 33584.4166 with a balance of 8e-05.
