Let's divide 203663 by 3
Let's see how many times 3 fits into 203663.

On to step 1:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Moving on to step 2:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 2 after subtracting 18 from 20.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtract 21 from 23 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

On to step 4:
When dividing 26 by 3, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 678.0
Deduct 24 from 26 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 5:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 6788.0
If we subtract 24 from 26, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

On to step 6:
3 goes into 23 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 67887.0
Subtract 21 from 23 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 67887.6
Deduct 18 from 20 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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 67887.66
Subtracting 18 from 20 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.

The final result is 67887.66 with a remainder of 0.002.
