Let's divide 720918 by 10
We want to figure out the number of times 720918 can be divided by 10.

On to step 1:
If we divide 7 by 10, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 10

Going ahead to step 2:
The number 10 fits into 72 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 70 from 72 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 10

On to step 3:
20 divided by 10 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 20 away from 20, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 10

Moving on to step 4:
When dividing 9 by 10, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 720.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

Step 5:
The number 10 fits into 91 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7209.0
Deduct 90 from 91 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 10

Going ahead to step 6:
10 can be fit into 18 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 72091.0
If we subtract 10 from 18, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
If we divide 80 by 10, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 72091.8
If we subtract 80 from 80, 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.

Step 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72091.8
Subtracting 0 from 0 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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72091.8
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 72091.8 with a balance of 0.0.
