Moving on to step 1:
80 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 80

Moving on to step 2:
58 divided by 80 is 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 80

Step 3:
If we divide 586 by 80, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 560 from 586 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 80

Step 4:
262 divided by 80 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtract 240 from 262 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 80

On to step 5:
When dividing 221 by 80, we get 2 with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
Subtracting 160 from 221 leaves us with 61.
Take the next digit (1) from the dividend and append it to 61, then repeat: 611 / 80

Going ahead to step 6:
80 goes into 611 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 7327.0
Subtracting 560 from 611 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 80

Advancing to step 7:
When dividing 519 by 80, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 73276.0
Deduct 480 from 519 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 80

Advancing to step 8:
80 can be fit into 391 4 times, resulting in a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 732764.0
The remainder is 71 after subtracting 320 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
710 divided by 80 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 732764.8
Subtracting 640 from 710 leaves us with 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 10:
700 divided by 80 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 732764.88
If we subtract 640 from 700, 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.

Our division results in 732764.88 with a remaining 0.06.
