We look at the division of 720964 by 81 
We want to figure out the number of times 720964 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 81

Advancing to step 2:
81 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 81

Step 3:
If we divide 720 by 81, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 648 away from 720, we end up with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 81

Step 4:
The number 81 fits into 729 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 0 after subtracting 729 from 729.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 81

Let's proceed to step 5:
81 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 81

Let's proceed to step 6:
When dividing 64 by 81, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 8900.0
The remainder is 64 after subtracting 0 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
640 divided by 81 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 8900.7
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.

On to step 8:
When dividing 730 by 81, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8900.79
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 8900.79
Deduct 0 from 10 and we're left 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.

Let's proceed to step 10:
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: 8900.7901
If we take 81 away from 100, we end up 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.

Advancing to step 11:
190 divided by 81 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 8900.79012
The remainder is 28 after subtracting 162 from 190.
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 12:
81 goes into 280 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 8900.790123
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
81 goes into 370 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 8900.7901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
The number 81 fits into 460 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8900.79012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 8900.79012345 with a remainder of 5.5e-08.
