720423 divided by 1 
Let's see how many times 1 fits into 720423.

Advancing to step 1:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 2:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 2 away from 2, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Step 3:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 720.0
Subtract 0 from 0 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 7204.0
Deduct 4 from 4 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 5:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 72042.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 6:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 720423.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 720423.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 720423.0
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 final result is 720423.0 with a remainder of 0.0.
