We look at the division of 18345384 by 518 
We want to divide 18345384 by 518.

Going ahead to step 1:
518 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 518

Advancing to step 2:
The number 518 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 518

Going ahead to step 3:
When dividing 183 by 518, we get 0 with a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Bring next digit (4) of the dividend behind the 183 and repeat the process: 1834 / 518

Advancing to step 4:
1834 divided by 518 is 3 with a remainder of 280.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1554 from 1834, we get 280.
Fetch the next digit (5) from the dividend, attach it to 280 and continue: 2805 / 518

Going ahead to step 5:
518 can be fit into 2805 5 times, resulting in a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 2590 from 2805 to get 215.
Grab the next digit (3) from the dividend, add it to 215, then carry on: 2153 / 518

Step 6:
518 goes into 2153 4 times with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
If we take 2072 away from 2153, we end up with 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 518

Step 7:
If we divide 818 by 518, we get 1 and a remainder of 300.
The next digit of our result is 1. 
Result so far: 3541.0
If we take 518 away from 818, we end up with 300.
Append the next digit (4) from the dividend to 300 and continue with: 3004 / 518

Let's proceed to step 8:
518 can be fit into 3004 5 times, resulting in a remainder of 414.
The number 5 becomes the next digit in our result. 
Result so far: 35415.0
If we subtract 2590 from 3004, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 9:
518 can be fit into 4140 7 times, resulting in a remainder of 514.
The next digit of our result is 7. 
Result so far: 35415.7
If we subtract 3626 from 4140, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Moving on to step 10:
If we divide 5140 by 518, we get 9 and a remainder of 478.
Record the quotient 9 as the next digit in the result. 
Result so far: 35415.79
Subtracting 4662 from 5140 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 11:
If we divide 4780 by 518, we get 9 and a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 35415.799
If we take 4662 away from 4780, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final result is 35415.799 with a remainder of 0.0118.
