We look at the division of 343547 by 18 
We're looking to find how many times 18 goes into 343547.

Step 1:
3 divided by 18 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 18

On 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
Deduct 18 from 34 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 18

Advancing to step 3:
The number 18 fits into 163 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 162 from 163, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 18

Moving on to step 4:
If we divide 15 by 18, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 18

Moving on to step 5:
18 goes into 154 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 1908.0
Deduct 144 from 154 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 18

Let's proceed to step 6:
18 can be fit into 107 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 19085.0
Deduct 90 from 107 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19085.9
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 19085.94
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
18 goes into 80 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 19085.944
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 19085.944, and the remainder is 0.0008.
