We divide 817720 by 81
We're looking to find how many times 81 goes into 817720.

Advancing to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 81

On to step 2:
81 goes into 81 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 81, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 81

Moving on to step 3:
81 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 81

On to step 4:
The number 81 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 81

Step 5:
772 divided by 81 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 1009.0
Subtracting 729 from 772 leaves us with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 81

Advancing to step 6:
81 goes into 430 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10095.0
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 81, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10095.3
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
If we divide 70 by 81, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10095.3
Subtract 0 from 70 to 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:
If we divide 700 by 81, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 10095.308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 81, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 10095.3086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 81 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 10095.30864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 10095.308641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 13:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 10095.3086419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
The number 81 fits into 610 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 10095.30864197
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 10095.30864197 and a remainder of 4.3e-08.
