856986 divided by 17 
We're looking to find how many times 17 goes into 856986.

Going ahead to step 1:
8 divided by 17 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 17

Advancing to step 2:
17 can be fit into 85 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 85 from 85, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 17

Step 3:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 17

Moving on to step 4:
The number 17 fits into 69 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 504.0
The remainder is 1 after subtracting 68 from 69.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 17

Moving on to step 5:
If we divide 18 by 17, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 5041.0
Subtracting 17 from 18 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 17

Step 6:
When dividing 16 by 17, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 50410.0
If we subtract 0 from 16, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 17, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 50410.9
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 50410.94
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 17 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 50410.941
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
17 goes into 30 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 50410.9411
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.

The quotient of the division is 50410.9411, and the remainder is 0.00013.
