721073 ÷ 30 
We're looking to find how many times 30 goes into 721073.

Moving on to step 1:
When dividing 7 by 30, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 30

Let's proceed to step 2:
72 divided by 30 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 72 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 30

Step 3:
The number 30 fits into 121 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 120 from 121 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 30

On to step 4:
10 divided by 30 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 240.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 30

Step 5:
30 can be fit into 107 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 2403.0
Subtract 90 from 107 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 30

Let's proceed to step 6:
The number 30 fits into 173 5 times, leaving a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 24035.0
The remainder is 23 after subtracting 150 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 30 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 24035.7
Deduct 210 from 230 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.

Advancing to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 24035.76
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 24035.766
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 24035.766, and the remainder is 0.002.
