170583 ÷ 85 
Our goal is to divide 170583 by 85.

Step 1:
1 divided by 85 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 85

Going ahead to step 2:
When dividing 17 by 85, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 85

Going ahead to step 3:
170 divided by 85 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 170 from 170, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 85

Step 4:
85 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 85

Let's proceed to step 5:
58 divided by 85 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 200.0
If we subtract 0 from 58, we get 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 85

Going ahead to step 6:
583 divided by 85 is 6 with a remainder of 73.
Write down 6 as next digit of the result. 
Result so far: 2006.0
Deduct 510 from 583 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
The number 85 fits into 730 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 2006.8
If we subtract 680 from 730, we 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.

Let's proceed to step 8:
85 goes into 500 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2006.85
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.

Step 9:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 2006.858
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 85 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 2006.8588
If we subtract 680 from 700, we get 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 result is 2006.8588 with a remainder of 0.0002.
