689077 divided by 81 
We want to divide 689077 by 81.

Moving on to step 1:
81 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 81

Moving on to step 2:
81 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 81

Step 3:
If we divide 689 by 81, we get 8 and a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 648 from 689, we get 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 81

Moving on to step 4:
If we divide 410 by 81, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 405 from 410, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 81

Moving on to step 5:
57 divided by 81 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 850.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 81

Advancing to step 6:
81 can be fit into 577 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 8507.0
If we take 567 away from 577, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 8507.1
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
81 goes into 190 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 8507.12
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
The number 81 fits into 280 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 8507.123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
If we divide 370 by 81, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 8507.1234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8507.12345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 8507.123456
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
640 divided by 81 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 8507.1234567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 14:
730 divided by 81 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 8507.12345679
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 8507.12345679 with a balance of 1e-09.
