We look at the division of 2402 by 3 
Our goal is to divide 2402 by 3.

Going ahead to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 2:
If we divide 24 by 3, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Moving on to step 3:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

On to step 4:
If we divide 2 by 3, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 800.0
The remainder is 2 after subtracting 0 from 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 5:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 800.6
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.

Moving on to step 6:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 800.66
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.

Our division results in 800.66 with a remaining 0.002.
