We look at the division of 721871 by 10 
Let's see how many times 10 fits into 721871.

Going ahead to step 1:
10 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 10

Moving on to step 2:
10 goes into 72 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 70 from 72, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 10

On to step 3:
When dividing 21 by 10, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtracting 20 from 21 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 10

Step 4:
The number 10 fits into 18 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 721.0
Subtracting 10 from 18 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 10

Going ahead to step 5:
If we divide 87 by 10, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 7218.0
If we subtract 80 from 87, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 10

Advancing to step 6:
If we divide 71 by 10, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 72187.0
The remainder is 1 after subtracting 70 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 72187.1
Deduct 10 from 10 and we're left 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.

Moving on to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72187.1
Deduct 0 from 0 and we're left 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:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 72187.1
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.

In conclusion, the division gives 72187.1 with a balance of 0.0.
