We're dividing 17880 by 45 
We want to figure out the number of times 17880 can be divided by 45.

Advancing to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 45

Advancing to step 2:
When dividing 17 by 45, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 45

Let's proceed to step 3:
45 can be fit into 178 3 times, resulting in a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 43 after subtracting 135 from 178.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 45

Step 4:
45 goes into 438 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 405 from 438 to get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 45

Going ahead to step 5:
When dividing 330 by 45, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 397.0
Deduct 315 from 330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 6:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 397.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 45 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 397.33
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 397.33 with a balance of 0.015.
