We're dividing 85842 by 17 
Let's see how many times 17 fits into 85842.

On to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 17

Let's proceed to step 2:
85 divided by 17 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 85 away from 85, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 17

Let's proceed to step 3:
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: 50.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 17

Going ahead to step 4:
The number 17 fits into 84 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 504.0
If we subtract 68 from 84, we get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 17

Step 5:
If we divide 162 by 17, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 5049.0
Subtract 153 from 162 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 6:
17 goes into 90 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5049.5
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 17 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 5049.52
Deduct 34 from 50 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.

Let's proceed to step 8:
17 goes into 160 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 5049.529
Subtract 153 from 160 to 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.

Going ahead to step 9:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 5049.5294
Subtract 68 from 70 to 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.

Moving on to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 5049.52941
Deduct 17 from 20 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
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: 5049.529411
Subtract 17 from 30 to get 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 final result is 5049.529411 with a remainder of 1.3e-06.
