403026 divided by 12 
We want to divide 403026 by 12.

On to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 12

Moving on to step 2:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 36 from 40 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

On to step 3:
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: 33.0
Subtract 36 from 43 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Advancing to step 4:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 335.0
Deduct 60 from 70 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

On to step 5:
12 goes into 102 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3358.0
Subtracting 96 from 102 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Going ahead to step 6:
12 can be fit into 66 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 33585.0
If we take 60 away from 66, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33585.5
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33585.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33585.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 33585.5, and the remainder is 0.0.
