Let's divide 85407 by 17
Let's see how many times 17 fits into 85407.

Going ahead to step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 17

Advancing to step 2:
If we divide 85 by 17, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 85 from 85 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 17

Step 3:
17 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 17

Going ahead to step 4:
17 can be fit into 40 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 502.0
Subtract 34 from 40 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 17

Moving on to step 5:
The number 17 fits into 67 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 5023.0
Deduct 51 from 67 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 6:
160 divided by 17 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 5023.9
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 17, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 5023.94
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
17 goes into 20 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 5023.941
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.

Going ahead to step 9:
17 goes into 30 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 5023.9411
Subtracting 17 from 30 leaves us 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.

Our division results in 5023.9411 with a remaining 0.00013.
