338903 divided by 12 
We want to figure out the number of times 338903 can be divided by 12.

Step 1:
3 divided by 12 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Moving on to step 2:
If we divide 33 by 12, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

On to step 3:
When dividing 98 by 12, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 2 after subtracting 96 from 98.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 12

Going ahead to step 4:
When dividing 29 by 12, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
The remainder is 5 after subtracting 24 from 29.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Let's proceed to step 5:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 2824.0
The remainder is 2 after subtracting 48 from 50.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 12

Let's proceed to step 6:
The number 12 fits into 23 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 28241.0
Subtract 12 from 23 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 28241.9
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.

Let's proceed to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 28241.91
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:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 28241.916
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 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 28241.9166
If we take 72 away from 80, we end up 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.

The final outcome is 28241.9166, with a leftover of 8e-05.
