We look at the division of 43287160 by 45 
We want to figure out the number of times 43287160 can be divided by 45.

Step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 45

Moving on to step 2:
If we divide 43 by 45, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 45

Let's proceed to step 3:
When dividing 432 by 45, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 27 after subtracting 405 from 432.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 45

Step 4:
When dividing 278 by 45, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 270 from 278, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 45

Let's proceed to step 5:
The number 45 fits into 87 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
Subtracting 45 from 87 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 45

Step 6:
45 can be fit into 421 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 9619.0
Subtract 405 from 421 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 45

Going ahead to step 7:
166 divided by 45 is 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 96193.0
Subtracting 135 from 166 leaves us with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 45

Going ahead to step 8:
45 can be fit into 310 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 961936.0
If we take 270 away from 310, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 961936.8
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 961936.88
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 961936.88 with a remainder of 0.04.
