We're dividing 721457 by 5 
We're looking to find how many times 5 goes into 721457.

Going ahead to step 1:
When dividing 7 by 5, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 7 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 5

On to step 2:
22 divided by 5 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 20 from 22 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 5

Step 3:
If we divide 21 by 5, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 20 from 21 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 5

Step 4:
14 divided by 5 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1442.0
If we subtract 10 from 14, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 5

Step 5:
When dividing 45 by 5, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 14429.0
The remainder is 0 after subtracting 45 from 45.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 5

Moving on to step 6:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 144291.0
If we take 5 away from 7, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 5, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 144291.4
Subtract 20 from 20 to 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 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 144291.4
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.

Step 9:
5 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 144291.4
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.

Our division results in 144291.4 with a remaining 0.0.
