Let's divide 721173 by 5
We want to divide 721173 by 5.

Step 1:
5 can be fit into 7 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 5 from 7, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 5

Step 2:
If we divide 22 by 5, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 20 from 22, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 5

Step 3:
5 goes into 21 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we take 20 away from 21, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 5

Moving on to step 4:
11 divided by 5 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1442.0
If we subtract 10 from 11, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 5

Going ahead to step 5:
The number 5 fits into 17 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 14423.0
Deduct 15 from 17 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 5

Advancing to step 6:
5 goes into 23 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 144234.0
Subtract 20 from 23 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 144234.6
Subtracting 30 from 30 leaves us 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.

Let's proceed to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 144234.6
Subtract 0 from 0 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.

Step 9:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 144234.6
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.

After the division, we end up with 144234.6 and a remainder of 0.0.
