855387 divided by 17 
We're looking to find how many times 17 goes into 855387.

Step 1:
When dividing 8 by 17, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 17

Let's proceed to step 2:
If we divide 85 by 17, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 85 from 85 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 17

On to step 3:
When dividing 5 by 17, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 17

Moving on to step 4:
17 can be fit into 53 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 503.0
Deduct 51 from 53 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 17

Going ahead to step 5:
28 divided by 17 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 5031.0
Deduct 17 from 28 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 17

Going ahead to step 6:
When dividing 117 by 17, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 50316.0
The remainder is 15 after subtracting 102 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
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: 50316.8
If we subtract 136 from 150, we get 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 8:
If we divide 140 by 17, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 50316.88
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 50316.88, with a leftover of 0.004.
