135945 ÷ 18 
We're looking to find how many times 18 goes into 135945.

Let's proceed to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 18

Advancing to step 2:
When dividing 13 by 18, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 18

Moving on to step 3:
If we divide 135 by 18, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 126 away from 135, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 18

Moving on to step 4:
18 goes into 99 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtract 90 from 99 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 18

On to step 5:
The number 18 fits into 94 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 755.0
Deduct 90 from 94 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 18

On to step 6:
If we divide 45 by 18, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 7552.0
Subtracting 36 from 45 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7552.5
If we take 90 away from 90, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7552.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 18 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7552.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 7552.5 with a balance of 0.0.
