We're dividing 839289 by 85 
We want to figure out the number of times 839289 can be divided by 85.

On to step 1:
The number 85 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.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 85

Moving on to step 2:
The number 85 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 85

Advancing to step 3:
85 can be fit into 839 9 times, resulting in a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 765 from 839 leaves us with 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 85

Going ahead to step 4:
85 can be fit into 742 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 680 from 742 leaves us with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 85

Step 5:
If we divide 628 by 85, we get 7 and a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 987.0
Deduct 595 from 628 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 85

Going ahead to step 6:
If we divide 339 by 85, we get 3 and a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 9873.0
The remainder is 84 after subtracting 255 from 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 7:
If we divide 840 by 85, we get 9 and a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 9873.9
Subtract 765 from 840 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 9873.98
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
85 goes into 700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 9873.988
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 9873.988, and the remainder is 0.002.
