We divide 729975 by 45
We want to divide 729975 by 45.

Moving on to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

Advancing to step 2:
72 divided by 45 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 45 from 72.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 45

Let's proceed to step 3:
45 can be fit into 279 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 9 after subtracting 270 from 279.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 45

Step 4:
If we divide 99 by 45, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Subtract 90 from 99 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 45

Advancing to step 5:
97 divided by 45 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 1622.0
The remainder is 7 after subtracting 90 from 97.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 45

Step 6:
45 can be fit into 75 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 16221.0
Deduct 45 from 75 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 45, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16221.6
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 45 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16221.66
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 16221.66 with a remainder of 0.03.
