723711 ÷ 45 
Our goal is to divide 723711 by 45.

Step 1:
45 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 45

Step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 72 and we're left with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 45

Moving on to step 3:
273 divided by 45 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 270 from 273 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 45

Advancing to step 4:
37 divided by 45 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we take 0 away from 37, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 45

Moving on to step 5:
45 goes into 371 8 times with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 1608.0
Subtracting 360 from 371 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 45

Moving on to step 6:
If we divide 111 by 45, we get 2 and a remainder of 21.
The next digit of our result is 2. 
Result so far: 16082.0
Subtract 90 from 111 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
45 can be fit into 210 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 16082.4
Deduct 180 from 210 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.

Advancing to step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 16082.46
Deduct 270 from 300 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.

Advancing to step 9:
If we divide 300 by 45, we get 6 and a remainder of 30.
The next digit of our result is 6. 
Result so far: 16082.466
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.

After the division, we end up with 16082.466 and a remainder of 0.003.
