344540 divided by 18 
We want to figure out the number of times 344540 can be divided by 18.

Step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 18

Step 2:
The number 18 fits into 34 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 18 from 34 leaves us with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 18

On to step 3:
If we divide 164 by 18, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 2 after subtracting 162 from 164.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

Moving on to step 4:
18 goes into 25 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 191.0
If we take 18 away from 25, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 18

Moving on to step 5:
When dividing 74 by 18, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1914.0
Subtracting 72 from 74 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 18

Moving on to step 6:
When dividing 20 by 18, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 19141.0
If we take 18 away from 20, we end up 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.

Moving on to step 7:
When dividing 20 by 18, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 19141.1
If we take 18 away from 20, we end up 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.

Advancing to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 19141.11
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 19141.11 with a remaining 0.002.
