617582 ÷ 18 
Let's see how many times 18 fits into 617582.

Step 1:
18 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 18

Moving on to step 2:
The number 18 fits into 61 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 7 after subtracting 54 from 61.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 18

Let's proceed to step 3:
When dividing 77 by 18, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 72 from 77, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 18

Advancing to step 4:
55 divided by 18 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 343.0
Subtracting 54 from 55 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

Moving on to step 5:
18 can be fit into 18 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 3431.0
If we subtract 18 from 18, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 18

Step 6:
If we divide 2 by 18, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 34310.0
If we subtract 0 from 2, 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.

Going ahead to step 7:
18 goes into 20 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 34310.1
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.

Going ahead to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 34310.11
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.

The final result is 34310.11 with a remainder of 0.002.
