721620 ÷ 72 
We want to divide 721620 by 72.

Moving on to step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 72

Let's proceed to step 2:
72 can be fit into 72 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 72 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 72

Going ahead to step 3:
1 divided by 72 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 72

Moving on to step 4:
The number 72 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 72

Moving on to step 5:
When dividing 162 by 72, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
The remainder is 18 after subtracting 144 from 162.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 72

Moving on to step 6:
When dividing 180 by 72, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10022.0
Deduct 144 from 180 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10022.5
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 72 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10022.5
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
72 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10022.5
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.

After the division, we end up with 10022.5 and a remainder of 0.0.
