We're dividing 715891 by 80 
We're looking to find how many times 80 goes into 715891.

Step 1:
80 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 80

Step 2:
The number 80 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 80

Let's proceed to step 3:
715 divided by 80 is 8 with a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 640 from 715 leaves us with 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 80

Moving on to step 4:
758 divided by 80 is 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 720 away from 758, we end up with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 80

Let's proceed to step 5:
When dividing 389 by 80, we get 4 with a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 894.0
Subtracting 320 from 389 leaves us with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 80

Going ahead to step 6:
80 can be fit into 691 8 times, resulting in a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 8948.0
The remainder is 51 after subtracting 640 from 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
80 can be fit into 510 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 8948.6
If we subtract 480 from 510, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 8948.63
If we subtract 240 from 300, 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 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 8948.637
Subtracting 560 from 600 leaves us 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8948.6375
The remainder is 0 after subtracting 400 from 400.
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.
Use 0 as the next digit of our solution. 
Result so far: 8948.6375
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.

On to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8948.6375
Subtract 0 from 0 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.

Our division results in 8948.6375 with a remaining 0.0.
