If we divide 64 by 821, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 821

Let's proceed to step 3:
When dividing 649 by 821, we get 0 with a remainder of 649.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 649 to get 649.
Append the next digit (0) from the dividend to 649 and continue with: 6490 / 821

Moving on to step 4:
821 can be fit into 6490 7 times, resulting in a remainder of 743.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5747 from 6490 to get 743.
Bring next digit (4) of the dividend behind the 743 and repeat the process: 7434 / 821

Let's proceed to step 5:
821 goes into 7434 9 times with a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 7389 from 7434 leaves us with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 821

Step 6:
821 goes into 457 0 times with a remainder of 457.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
If we subtract 0 from 457, we get 457.
Bring next digit (0) of the dividend behind the 457 and repeat the process: 4570 / 821

Let's proceed to step 7:
4570 divided by 821 is 5 with a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 7905.0
If we subtract 4105 from 4570, we get 465.
Include the next digit (8) from the dividend after 465, then repeat: 4658 / 821

Going ahead to step 8:
The number 821 fits into 4658 5 times, leaving a remainder of 553.
The number 5 becomes the next digit in our result. 
Result so far: 79055.0
If we take 4105 away from 4658, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
When dividing 5530 by 821, we get 6 with a remainder of 604.
The number 6 becomes the next digit in our result. 
Result so far: 79055.6
If we subtract 4926 from 5530, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 10:
The number 821 fits into 6040 7 times, leaving a remainder of 293.
The next digit of our result is 7. 
Result so far: 79055.67
Subtracting 5747 from 6040 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 11:
The number 821 fits into 2930 3 times, leaving a remainder of 467.
The next digit of our result is 3. 
Result so far: 79055.673
Deduct 2463 from 2930 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 12:
If we divide 4670 by 821, we get 5 and a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 79055.6735
Subtracting 4105 from 4670 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

On to step 13:
The number 821 fits into 5650 6 times, leaving a remainder of 724.
Record the quotient 6 as the next digit in the result. 
Result so far: 79055.67356
Subtracting 4926 from 5650 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 14:
The number 821 fits into 7240 8 times, leaving a remainder of 672.
The next digit of our result is 8. 
Result so far: 79055.673568
Subtract 6568 from 7240 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 15:
If we divide 6720 by 821, we get 8 and a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 79055.6735688
If we subtract 6568 from 6720, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 79055.6735688 with a remainder of 1.52e-06.
