We're dividing 680458 by 85 
Let's see how many times 85 fits into 680458.

On to step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 85

Let's proceed to step 2:
When dividing 68 by 85, we get 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 85

On to step 3:
The number 85 fits into 680 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 0 after subtracting 680 from 680.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 85

On to step 4:
85 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 85

Moving on to step 5:
85 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 800.0
If we subtract 0 from 45, we get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 85

Step 6:
The number 85 fits into 458 5 times, leaving a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 8005.0
If we take 425 away from 458, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
85 can be fit into 330 3 times, resulting in a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 8005.3
If we subtract 255 from 330, we 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.

Going ahead to step 8:
85 goes into 750 8 times with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8005.38
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.

Moving on to step 9:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8005.388
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.

After the division, we end up with 8005.388 and a remainder of 0.002.
