We look at the division of 856809 by 85 
We want to divide 856809 by 85.

Let's proceed to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 85

On to step 2:
The number 85 fits into 85 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 85 away from 85, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 85

Let's proceed to step 3:
The number 85 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 85

On to step 4:
85 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 85

Step 5:
If we divide 680 by 85, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 1008.0
If we take 680 away from 680, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 85

Let's proceed to step 6:
85 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 10080.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 85, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10080.1
If we take 85 away from 90, we end up 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.

Let's proceed to step 8:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10080.1
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10080.105
Subtract 425 from 500 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.

Step 10:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 10080.1058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
85 goes into 700 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 10080.10588
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 quotient of the division is 10080.10588, and the remainder is 2e-05.
