Let's divide 43985878 by 45
We're looking to find how many times 45 goes into 43985878.

Moving on to step 1:
4 divided by 45 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 45

Moving on to step 2:
The number 45 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 45

Going ahead to step 3:
45 can be fit into 439 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 405 away from 439, we end up with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 45

Moving on to step 4:
45 goes into 348 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 315 from 348 leaves us with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 45

Moving on to step 5:
If we divide 335 by 45, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 977.0
If we take 315 away from 335, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 45

On to step 6:
The number 45 fits into 208 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 9774.0
Subtract 180 from 208 to get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 45

Let's proceed to step 7:
45 goes into 287 6 times with a remainder of 17.
The next digit of our result is 6. 
Result so far: 97746.0
If we subtract 270 from 287, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 45

Advancing to step 8:
45 can be fit into 178 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 977463.0
The remainder is 43 after subtracting 135 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
45 goes into 430 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 977463.9
Subtract 405 from 430 to 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 10:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 977463.95
If we take 225 away from 250, we end up 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 11:
45 goes into 250 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 977463.955
If we take 225 away from 250, we end up 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.

Our division results in 977463.955 with a remaining 0.0025.
