We divide 80511 by 86
Our goal is to divide 80511 by 86.

On to step 1:
8 divided by 86 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 86

Going ahead to step 2:
If we divide 80 by 86, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 86

Step 3:
86 goes into 805 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 31 after subtracting 774 from 805.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 86

On to step 4:
311 divided by 86 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 258 from 311, we get 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 86

Advancing to step 5:
The number 86 fits into 531 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 936.0
Subtract 516 from 531 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
86 can be fit into 150 1 times, resulting in a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 936.1
Subtract 86 from 150 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 936.17
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 86, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 936.174
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 936.1744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 936.1744 and a remainder of 0.00016.
