We look at the division of 6816 by 75 
We want to divide 6816 by 75.

Going ahead to step 1:
75 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 75

On to step 2:
75 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 75

Step 3:
If we divide 681 by 75, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 675 from 681, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 75

Going ahead to step 4:
When dividing 66 by 75, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 66 after subtracting 0 from 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 5:
75 can be fit into 660 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 90.8
If we take 600 away from 660, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 6:
600 divided by 75 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 90.88
Subtract 600 from 600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 90.88 with a remaining 0.0.
