80512 ÷ 86 
We're looking to find how many times 86 goes into 80512.

On to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 86

On to step 2:
86 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 86

Going ahead to step 3:
The number 86 fits into 805 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 774 from 805, we get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 86

Moving on to step 4:
When dividing 311 by 86, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 258 from 311 leaves us with 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 86

Step 5:
If we divide 532 by 86, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 936.0
Subtracting 516 from 532 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 6:
When dividing 160 by 86, we get 1 with a remainder of 74.
The next digit of our result is 1. 
Result so far: 936.1
Subtracting 86 from 160 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
When dividing 740 by 86, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 936.18
Subtracting 688 from 740 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
520 divided by 86 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 936.186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 936.186
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
86 can be fit into 400 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 936.18604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 936.186046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 936.1860465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 86, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 936.18604651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 936.18604651 and a remainder of 1.4e-08.
