Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 62843.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 628438.0
The remainder is 0 after subtracting 8 from 8.
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 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 628438.0
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.

Going ahead to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 628438.0
Subtracting 0 from 0 leaves us with 0.
