We divide 904040 by 80
We want to divide 904040 by 80.

Step 1:
80 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 80

Moving on to step 2:
80 can be fit into 90 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 90 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 80

Let's proceed to step 3:
The number 80 fits into 104 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 80 from 104 to get 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 80

Let's proceed to step 4:
80 goes into 240 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 240 from 240 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 80

Advancing to step 5:
4 divided by 80 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 1130.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 80

Let's proceed to step 6:
40 divided by 80 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11300.0
If we subtract 0 from 40, 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.

Step 7:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11300.5
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11300.5
Subtracting 0 from 0 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.

Step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11300.5
If we subtract 0 from 0, we get 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 outcome is 11300.5, with a leftover of 0.0.
