Let's divide 432903 by 12
Our goal is to divide 432903 by 12.

On to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

On to step 2:
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: 3.0
If we subtract 36 from 43, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 12

Moving on to step 3:
If we divide 72 by 12, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 0 after subtracting 72 from 72.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Moving on to step 4:
9 divided by 12 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 360.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

On to step 5:
90 divided by 12 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 3607.0
If we subtract 84 from 90, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Advancing to step 6:
12 can be fit into 63 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 36075.0
If we subtract 60 from 63, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 36075.2
Subtracting 24 from 30 leaves us 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.

Going ahead to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 36075.25
If we take 60 away from 60, we end up 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.

Let's proceed to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36075.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36075.25
Subtract 0 from 0 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.

The final outcome is 36075.25, with a leftover of 0.0.
