We're dividing 723144 by 1 
We want to divide 723144 by 1.

Step 1:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Going ahead to step 2:
2 divided by 1 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
3 divided by 1 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 723.0
The remainder is 0 after subtracting 3 from 3.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Moving on to step 4:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 7231.0
If we subtract 1 from 1, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Advancing to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 72314.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Step 6:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 723144.0
If we subtract 4 from 4, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 723144.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 723144.0
If we take 0 away from 0, we end up 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.

The quotient of the division is 723144.0, and the remainder is 0.0.
