We look at the division of 71391 by 8 
We're looking to find how many times 8 goes into 71391.

Moving on to step 1:
When dividing 7 by 8, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 8

Going ahead to step 2:
8 goes into 71 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 64 from 71 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 8

Let's proceed to step 3:
8 can be fit into 73 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 72 away from 73, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 8

Let's proceed to step 4:
8 can be fit into 19 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 892.0
Subtracting 16 from 19 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 8

Step 5:
31 divided by 8 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 8923.0
The remainder is 7 after subtracting 24 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8923.8
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 8923.87
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 8, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8923.875
If we take 40 away from 40, we end up 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.

Advancing to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8923.875
If we subtract 0 from 0, we 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.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8923.875
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.

In conclusion, the division gives 8923.875 with a balance of 0.0.
