We look at the division of 842508 by 18 
We want to figure out the number of times 842508 can be divided by 18.

Moving on to step 1:
18 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 18

Let's proceed to step 2:
18 goes into 84 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 72 from 84 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 18

Let's proceed to step 3:
If we divide 122 by 18, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 14 after subtracting 108 from 122.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 18

Going ahead to step 4:
The number 18 fits into 145 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 468.0
Deduct 144 from 145 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 18

Going ahead to step 5:
The number 18 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4680.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 18

Moving on to step 6:
18 can be fit into 108 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 46806.0
The remainder is 0 after subtracting 108 from 108.
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 7:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 46806.0
If we subtract 0 from 0, we 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.

Advancing to step 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 46806.0
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.

The quotient of the division is 46806.0, and the remainder is 0.0.
