We look at the division of 668367 by 81 
Let's see how many times 81 fits into 668367.

On to step 1:
6 divided by 81 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 81

Step 2:
The number 81 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 81

Going ahead to step 3:
81 can be fit into 668 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 648 from 668 and we're left with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 81

Let's proceed to step 4:
When dividing 203 by 81, we get 2 with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 162 from 203 and we're left with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 81

Let's proceed to step 5:
The number 81 fits into 416 5 times, leaving a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
Subtracting 405 from 416 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 81

On to step 6:
81 goes into 117 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 8251.0
Subtract 81 from 117 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
81 goes into 360 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 8251.4
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 81 fits into 360 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 8251.44
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 8251.44 and a remainder of 0.036.
