Let's divide 904039 by 80
Let's see how many times 80 fits into 904039.

Moving on to step 1:
80 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 80

Let's proceed to step 2:
90 divided by 80 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 80 away from 90, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 80

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.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 80

Moving on to step 4:
The number 80 fits into 240 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 240 away from 240, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 80

Moving on to step 5:
80 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1130.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 80

Going ahead to step 6:
80 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 11300.0
Deduct 0 from 39 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
390 divided by 80 is 4 with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 11300.4
The remainder is 70 after subtracting 320 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 11300.48
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 11300.487
If we take 560 away from 600, 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.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11300.4875
Subtract 400 from 400 to 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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11300.4875
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.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11300.4875
Deduct 0 from 0 and we're left 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.

The final result is 11300.4875 with a remainder of 0.0.
