Let's divide 203963 by 3
We want to figure out the number of times 203963 can be divided by 3.

Going ahead to step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Let's proceed to step 2:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 18 from 20 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Advancing to step 3:
If we divide 23 by 3, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 2 after subtracting 21 from 23.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 4:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 679.0
If we take 27 away from 29, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Moving on to step 5:
When dividing 26 by 3, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 6798.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Advancing to step 6:
3 goes into 23 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 67987.0
Subtracting 21 from 23 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.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 67987.6
If we subtract 18 from 20, we 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.

Step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 67987.66
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.

The quotient of the division is 67987.66, and the remainder is 0.002.
