We're dividing 170039 by 89 
We want to divide 170039 by 89.

Advancing to step 1:
1 divided by 89 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 89

Advancing to step 2:
17 divided by 89 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 89

Going ahead to step 3:
If we divide 170 by 89, we get 1 and a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 89 from 170 leaves us with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 89

Let's proceed to step 4:
89 goes into 810 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 19.0
If we take 801 away from 810, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 89

On to step 5:
When dividing 93 by 89, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 191.0
Subtract 89 from 93 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 89

Step 6:
49 divided by 89 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 1910.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
89 can be fit into 490 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1910.5
Deduct 445 from 490 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
450 divided by 89 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1910.55
If we subtract 445 from 450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 1910.55 with a remainder of 0.005.
