We look at the division of 404558 by 80 
We want to divide 404558 by 80.

Step 1:
When dividing 4 by 80, we get 0 with 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.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 80

Going ahead to step 2:
When dividing 40 by 80, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 80

Moving on to step 3:
The number 80 fits into 404 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 400 from 404 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 80

Advancing to step 4:
45 divided by 80 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 80

Advancing to step 5:
455 divided by 80 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtracting 400 from 455 leaves us with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 80

Going ahead to step 6:
80 goes into 558 6 times with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 5056.0
If we take 480 away from 558, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
When dividing 780 by 80, we get 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 5056.9
If we subtract 720 from 780, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 5056.97
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5056.975
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.

Going ahead to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5056.975
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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5056.975
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.

Our division results in 5056.975 with a remaining 0.0.
