We look at the division of 718178 by 80 
We want to divide 718178 by 80.

Step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 80

Let's proceed to step 2:
If we divide 71 by 80, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 80

Going ahead to step 3:
718 divided by 80 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 640 from 718, we get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 80

Advancing to step 4:
When dividing 781 by 80, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 720 from 781 leaves us with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 80

Advancing to step 5:
When dividing 617 by 80, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 897.0
If we take 560 away from 617, we end up with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 80

Advancing to step 6:
The number 80 fits into 578 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 8977.0
Deduct 560 from 578 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 80, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8977.2
Deduct 160 from 180 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 8977.22
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 8977.22 with a remainder of 0.04.
