71234 divided by 80 
We want to divide 71234 by 80.

Going ahead to step 1:
80 goes into 7 0 times with 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.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 80

Moving on to step 2:
When dividing 71 by 80, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 80

Let's proceed to step 3:
If we divide 712 by 80, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 640 from 712 and we're left with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 80

Moving on to step 4:
80 can be fit into 723 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 720 away from 723, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 80

Going ahead to step 5:
34 divided by 80 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 890.0
Subtracting 0 from 34 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 6:
340 divided by 80 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 890.4
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 890.42
Subtracting 160 from 200 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.

On to step 8:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 890.425
If we subtract 400 from 400, 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.

Going ahead to step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 890.425
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.

Going ahead to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 890.425
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.

The final outcome is 890.425, with a leftover of 0.0.
