We look at the division of 852009 by 85 
Let's see how many times 85 fits into 852009.

Let's proceed to step 1:
The number 85 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 85

Let's proceed to step 2:
85 can be fit into 85 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 85 away from 85, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 85

Let's proceed to step 3:
2 divided by 85 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 85

Let's proceed to step 4:
If we divide 20 by 85, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 85

Step 5:
The number 85 fits into 200 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 1002.0
Deduct 170 from 200 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 85

On to step 6:
The number 85 fits into 309 3 times, leaving a remainder of 54.
The next digit of our result is 3. 
Result so far: 10023.0
The remainder is 54 after subtracting 255 from 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
When dividing 540 by 85, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 10023.6
Subtract 510 from 540 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 85 fits into 300 3 times, leaving a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 10023.63
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
450 divided by 85 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10023.635
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 10023.6352
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
The number 85 fits into 800 9 times, leaving a remainder of 35.
The next digit of our result is 9. 
Result so far: 10023.63529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
When dividing 350 by 85, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 10023.635294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 10023.6352941
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
When dividing 150 by 85, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 10023.63529411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 10023.63529411 with a remainder of 6.5e-08.
