782878 ÷ 81 
Let's see how many times 81 fits into 782878.

On to step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 81

Going ahead to step 2:
When dividing 78 by 81, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 81

Step 3:
81 goes into 782 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 9.0
If we take 729 away from 782, we end up with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 81

Advancing to step 4:
If we divide 538 by 81, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 96.0
If we take 486 away from 538, we end up with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 81

Moving on to step 5:
If we divide 527 by 81, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 966.0
If we subtract 486 from 527, we get 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 81

Moving on to step 6:
81 goes into 418 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 9665.0
The remainder is 13 after subtracting 405 from 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 81, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9665.1
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 8:
The number 81 fits into 490 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9665.16
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 81 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9665.16
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
81 goes into 400 4 times with a remainder of 76.
The next digit of our result is 4. 
Result so far: 9665.1604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
760 divided by 81 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9665.16049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
81 goes into 310 3 times with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 9665.160493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 13:
670 divided by 81 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 9665.1604938
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
81 can be fit into 220 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 9665.16049382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 9665.16049382 with a remaining 5.8e-08.
