We divide 721800 by 9
Let's see how many times 9 fits into 721800.

Step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 9

Moving on to step 2:
9 goes into 72 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 72 away from 72, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

Step 3:
9 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 9

Moving on to step 4:
When dividing 18 by 9, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 802.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 9

Moving on to step 5:
0 divided by 9 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8020.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Moving on to step 6:
0 divided by 9 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80200.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
9 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80200.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
9 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80200.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 80200.0, and the remainder is 0.0.
