We're dividing 709680 by 81 
We want to figure out the number of times 709680 can be divided by 81.

Going ahead to step 1:
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: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 81

Step 2:
If we divide 70 by 81, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 81

Let's proceed to step 3:
The number 81 fits into 709 8 times, leaving a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 61 after subtracting 648 from 709.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 81

Step 4:
81 can be fit into 616 7 times, resulting in a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 567 from 616 and we're left with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 81

Let's proceed to step 5:
When dividing 498 by 81, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 876.0
Subtracting 486 from 498 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 81

Let's proceed to step 6:
81 goes into 120 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 8761.0
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
The number 81 fits into 390 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8761.4
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
81 goes into 660 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8761.48
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 81, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 8761.481
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
If we divide 390 by 81, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8761.4814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8761.48148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
The number 81 fits into 120 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 8761.481481
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
390 divided by 81 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8761.4814814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
If we divide 660 by 81, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8761.48148148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8761.48148148 with a remaining 1.2e-08.
