Let's divide 721002 by 81
Let's see how many times 81 fits into 721002.

On to step 1:
7 divided by 81 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 81

Going ahead to step 2:
72 divided by 81 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 81

Step 3:
The number 81 fits into 721 8 times, leaving a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 648 from 721 and we're left with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 81

Going ahead to step 4:
If we divide 730 by 81, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 729 from 730, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 81

Advancing to step 5:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 890.0
If we subtract 0 from 10, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 81

Let's proceed to step 6:
The number 81 fits into 102 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 8901.0
The remainder is 21 after subtracting 81 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
81 goes into 210 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 8901.2
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
81 goes into 480 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 8901.25
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 81, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8901.259
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
81 goes into 210 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 8901.2592
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 81, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 8901.25925
Subtract 405 from 480 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
81 goes into 750 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 8901.259259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8901.2592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8901.25925925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 8901.25925925 with a remainder of 7.5e-08.
