We look at the division of 715311 by 80 
Let's see how many times 80 fits into 715311.

Moving on to 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

Advancing to step 2:
When dividing 71 by 80, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 80

Advancing to step 3:
If we divide 715 by 80, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 640 from 715 and we're left with 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 80

On to step 4:
80 goes into 753 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 720 away from 753, we end up with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 80

Let's proceed to step 5:
The number 80 fits into 331 4 times, leaving a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 894.0
Subtracting 320 from 331 leaves us with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 80

Moving on to step 6:
111 divided by 80 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 8941.0
The remainder is 31 after subtracting 80 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
The number 80 fits into 310 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 8941.3
If we subtract 240 from 310, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 8941.38
Subtracting 640 from 700 leaves us 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.

Going ahead to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 8941.387
If we subtract 560 from 600, 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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8941.3875
Subtracting 400 from 400 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 11:
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: 8941.3875
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.

On to step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8941.3875
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.

The quotient of the division is 8941.3875, and the remainder is 0.0.
