We look at the division of 872086 by 17 
We want to figure out the number of times 872086 can be divided by 17.

Step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 17

On to step 2:
87 divided by 17 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 85 from 87, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 17

On to step 3:
When dividing 22 by 17, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 17 from 22 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 17

Moving on to step 4:
17 goes into 50 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 512.0
Subtract 34 from 50 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 17

Step 5:
The number 17 fits into 168 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 5129.0
If we take 153 away from 168, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 17

Step 6:
If we divide 156 by 17, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 51299.0
If we take 153 away from 156, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 17, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 51299.1
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
The number 17 fits into 130 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 51299.17
Deduct 119 from 130 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 17 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 51299.176
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
17 goes into 80 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 51299.1764
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
17 goes into 120 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 51299.17647
Subtract 119 from 120 to get 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 12:
17 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 51299.17647
Subtracting 0 from 10 leaves us 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.

Step 13:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 51299.1764705
Deduct 85 from 100 and we're left 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.

Advancing to step 14:
When dividing 150 by 17, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 51299.17647058
Deduct 136 from 150 and we're left 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.

In conclusion, the division gives 51299.17647058 with a balance of 1.4e-08.
