We look at the division of 810012 by 86 
We're looking to find how many times 86 goes into 810012.

Let's proceed to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 86

Step 2:
86 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 86

Step 3:
810 divided by 86 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 774 from 810 and we're left with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 86

On to step 4:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtracting 344 from 360 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 86

Step 5:
If we divide 161 by 86, we get 1 and a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 941.0
If we take 86 away from 161, we end up with 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 86

Step 6:
752 divided by 86 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 9418.0
If we take 688 away from 752, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
When dividing 640 by 86, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 9418.7
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.

Going ahead to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9418.74
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 9418.744
The remainder is 16 after subtracting 344 from 360.
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 9418.744 and a remainder of 0.0016.
