We look at the division of 820442 by 85 
Let's see how many times 85 fits into 820442.

Step 1:
The number 85 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 85

On to step 2:
The number 85 fits into 82 0 times, leaving a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 85

Step 3:
When dividing 820 by 85, we get 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 765 from 820 leaves us with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 85

Step 4:
The number 85 fits into 554 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we take 510 away from 554, we end up with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 85

On to step 5:
The number 85 fits into 444 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 965.0
If we take 425 away from 444, we end up with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 85

Step 6:
192 divided by 85 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 9652.0
Subtract 170 from 192 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
220 divided by 85 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 9652.2
Subtract 170 from 220 to 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.

On to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 9652.25
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 9652.258
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 85, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 9652.2588
Deduct 680 from 700 and we're left with 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 9652.2588 with a remainder of 0.0002.
