We're dividing 64085824 by 721 
We want to divide 64085824 by 721.

On to step 1:
6 divided by 721 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 721

Going ahead to step 2:
721 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 721

Moving on to step 3:
721 goes into 640 0 times with a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 640 after subtracting 0 from 640.
Include the next digit (8) from the dividend after 640, then repeat: 6408 / 721

On to step 4:
721 can be fit into 6408 8 times, resulting in a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 640 after subtracting 5768 from 6408.
Append the next digit (5) from the dividend to 640 and continue with: 6405 / 721

Step 5:
The number 721 fits into 6405 8 times, leaving a remainder of 637.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 5768 from 6405 and we're left with 637.
Bring next digit (8) of the dividend behind the 637 and repeat the process: 6378 / 721

Moving on to step 6:
The number 721 fits into 6378 8 times, leaving a remainder of 610.
Write down 8 as next digit of the result. 
Result so far: 888.0
If we subtract 5768 from 6378, we get 610.
Include the next digit (2) from the dividend after 610, then repeat: 6102 / 721

Moving on to step 7:
If we divide 6102 by 721, we get 8 and a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 8888.0
Subtract 5768 from 6102 to get 334.
Fetch the next digit (4) from the dividend, attach it to 334 and continue: 3344 / 721

Let's proceed to step 8:
3344 divided by 721 is 4 with a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 88884.0
Subtract 2884 from 3344 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 9:
4600 divided by 721 is 6 with a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 88884.6
Deduct 4326 from 4600 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
The number 721 fits into 2740 3 times, leaving a remainder of 577.
Put 3 as the next digit of the answer. 
Result so far: 88884.63
If we take 2163 away from 2740, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 11:
The number 721 fits into 5770 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 88884.638
The remainder is 2 after subtracting 5768 from 5770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
721 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 88884.638
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
721 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 88884.638
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 88884.638 with a remainder of 0.0002.
