We look at the division of 81512 by 85 
We want to figure out the number of times 81512 can be divided by 85.

Moving on to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 85

Step 2:
If we divide 81 by 85, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 85

Let's proceed to step 3:
815 divided by 85 is 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 765 from 815, we get 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 85

On to step 4:
85 goes into 501 5 times with a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 425 away from 501, we end up with 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 85

Going ahead to step 5:
When dividing 762 by 85, we get 8 with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 958.0
If we take 680 away from 762, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 6:
85 goes into 820 9 times with a remainder of 55.
The next digit of our result is 9. 
Result so far: 958.9
If we take 765 away from 820, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
The number 85 fits into 550 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 958.96
Subtract 510 from 550 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.

Moving on to step 8:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 958.964
Subtract 340 from 400 to 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.

On to step 9:
When dividing 600 by 85, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 958.9647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 85, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 958.9647
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
85 goes into 500 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 958.964705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 958.9647058
Deduct 680 from 750 and we're left 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.

Moving on to step 13:
85 goes into 700 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 958.96470588
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 958.96470588, with a leftover of 2e-08.
