We're dividing 86864 by 17 
We're looking to find how many times 17 goes into 86864.

Step 1:
8 divided by 17 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 17

Let's proceed to step 2:
86 divided by 17 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 85 away from 86, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 17

Advancing to step 3:
17 can be fit into 18 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 17 from 18 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 17

Going ahead to step 4:
17 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 17

Advancing to step 5:
If we divide 164 by 17, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 5109.0
If we subtract 153 from 164, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 6:
The number 17 fits into 110 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 5109.6
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
17 can be fit into 80 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 5109.64
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 5109.647
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
17 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5109.647
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
17 goes into 100 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5109.64705
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 5109.647058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
140 divided by 17 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5109.6470588
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 5109.6470588 with a balance of 4e-08.
