340660 divided by 18 
We're looking to find how many times 18 goes into 340660.

Step 1:
3 divided by 18 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 18

Let's proceed to step 2:
The number 18 fits into 34 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 18 from 34, we get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 18

Let's proceed to step 3:
160 divided by 18 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 16 after subtracting 144 from 160.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 18

Moving on to step 4:
18 goes into 166 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 189.0
The remainder is 4 after subtracting 162 from 166.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 18

Advancing to step 5:
46 divided by 18 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 1892.0
Deduct 36 from 46 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 18

Moving on to step 6:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 18925.0
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 18, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 18925.5
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 18925.55
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 18925.55 with a remaining 0.01.
