Let's divide 81543680 by 817
Let's see how many times 817 fits into 81543680.

Advancing to step 1:
When dividing 8 by 817, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 817

Let's proceed to step 2:
81 divided by 817 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 817

Moving on to step 3:
The number 817 fits into 815 0 times, leaving a remainder of 815.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 815 and we're left with 815.
Append the next digit (4) from the dividend to 815 and continue with: 8154 / 817

Advancing to step 4:
8154 divided by 817 is 9 with a remainder of 801.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7353 from 8154 to get 801.
Grab the next digit (3) from the dividend, add it to 801, then carry on: 8013 / 817

Step 5:
817 can be fit into 8013 9 times, resulting in a remainder of 660.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 7353 from 8013 to get 660.
Take the next digit (6) from the dividend and append it to 660, then repeat: 6606 / 817

Step 6:
If we divide 6606 by 817, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 998.0
If we take 6536 away from 6606, we end up with 70.
Append the next digit (8) from the dividend to 70 and continue with: 708 / 817

On to step 7:
708 divided by 817 is 0 with a remainder of 708.
Record the quotient 0 as the next digit in the result. 
Result so far: 9980.0
If we take 0 away from 708, we end up with 708.
Include the next digit (0) from the dividend after 708, then repeat: 7080 / 817

On to step 8:
7080 divided by 817 is 8 with a remainder of 544.
Write down 8 as next digit of the result. 
Result so far: 99808.0
Subtracting 6536 from 7080 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 9:
817 can be fit into 5440 6 times, resulting in a remainder of 538.
Use 6 as the next digit of our solution. 
Result so far: 99808.6
The remainder is 538 after subtracting 4902 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 10:
817 goes into 5380 6 times with a remainder of 478.
The number 6 becomes the next digit in our result. 
Result so far: 99808.66
If we take 4902 away from 5380, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

The quotient of the division is 99808.66, and the remainder is 0.478.
