We're dividing 18340 by 45 
We're looking to find how many times 45 goes into 18340.

On to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 45

Step 2:
18 divided by 45 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 45

Going ahead to step 3:
45 goes into 183 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 3 after subtracting 180 from 183.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 45

Moving on to step 4:
45 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 34, we get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 45

Going ahead to step 5:
If we divide 340 by 45, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
If we subtract 315 from 340, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 6:
If we divide 250 by 45, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 407.5
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
When dividing 250 by 45, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 407.55
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 407.55 with a balance of 0.025.
