40440 divided by 80 
Let's see how many times 80 fits into 40440.

Advancing to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 80

Advancing to step 2:
80 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 80

Going ahead to step 3:
If we divide 404 by 80, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 400 from 404 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 80

Moving on to step 4:
When dividing 44 by 80, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 44 to get 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 80

Moving on to step 5:
80 goes into 440 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 505.0
Deduct 400 from 440 and we're left 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.

Advancing to step 6:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 505.5
Subtracting 400 from 400 leaves us 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.

Let's proceed to step 7:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 505.5
If we take 0 away from 0, 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 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 505.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 505.5 with a remainder of 0.0.
