261340 divided by 18 
Let's see how many times 18 fits into 261340.

On to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 18

Let's proceed to step 2:
26 divided by 18 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 18 from 26 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 18

Going ahead to step 3:
When dividing 81 by 18, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 72 away from 81, we end up with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 18

Let's proceed to step 4:
When dividing 93 by 18, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 145.0
Subtract 90 from 93 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 18

Advancing to step 5:
34 divided by 18 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1451.0
If we subtract 18 from 34, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 18

Going ahead to step 6:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 14518.0
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 18 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14518.8
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14518.88
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 14518.88, with a leftover of 0.016.
