Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 42

Going ahead to step 2:
42 goes into 83 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 83 leaves us with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 42

Going ahead to step 3:
42 goes into 413 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 378 from 413 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 42

Let's proceed to step 4:
354 divided by 42 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
The remainder is 18 after subtracting 336 from 354.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 42

Moving on to step 5:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1984.0
If we subtract 168 from 180, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 42

Going ahead to step 6:
The number 42 fits into 126 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 19843.0
The remainder is 0 after subtracting 126 from 126.
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:
The number 42 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19843.0
Subtract 0 from 0 to get 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:
42 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19843.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 19843.0 with a remaining 0.0.
