We look at the division of 935404 by 80 
We're looking to find how many times 80 goes into 935404.

On to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 80

Advancing to step 2:
80 can be fit into 93 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 80 from 93 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 80

Step 3:
135 divided by 80 is 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 55 after subtracting 80 from 135.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 80

Let's proceed to step 4:
80 goes into 554 6 times with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 480 from 554, we get 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 80

On to step 5:
The number 80 fits into 740 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 1169.0
Subtracting 720 from 740 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 80

Let's proceed to step 6:
The number 80 fits into 204 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11692.0
Subtract 160 from 204 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
80 can be fit into 440 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 11692.5
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.

On to step 8:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11692.55
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.

The quotient of the division is 11692.55, and the remainder is 0.0.
