Let's divide 721730 by 45
Our goal is to divide 721730 by 45.

Advancing to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

On to step 2:
45 can be fit into 72 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 72 to get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 45

On to step 3:
If we divide 271 by 45, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 270 from 271 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 45

Advancing to step 4:
45 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 160.0
Subtract 0 from 17 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 45

Going ahead to step 5:
45 goes into 173 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 1603.0
If we subtract 135 from 173, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 45

Let's proceed to step 6:
If we divide 380 by 45, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 16038.0
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 16038.4
Subtract 180 from 200 to 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.

Moving on to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 16038.44
Subtracting 180 from 200 leaves us 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.

After the division, we end up with 16038.44 and a remainder of 0.02.
