We look at the division of 723729 by 45 
Let's see how many times 45 fits into 723729.

Let's proceed to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 45

Let's proceed to step 2:
72 divided by 45 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 27 after subtracting 45 from 72.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 45

Let's proceed to step 3:
When dividing 273 by 45, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 270 from 273 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 45

Moving on to step 4:
If we divide 37 by 45, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 45

Going ahead to step 5:
If we divide 372 by 45, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1608.0
If we take 360 away from 372, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 45

Advancing to step 6:
129 divided by 45 is 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 16082.0
Subtract 90 from 129 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 45, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 16082.8
If we subtract 360 from 390, 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.

Going ahead to step 8:
45 goes into 300 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 16082.86
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.

Going ahead to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 16082.866
Subtracting 270 from 300 leaves us 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.

Our division results in 16082.866 with a remaining 0.003.
