We look at the division of 720163 by 9 
We want to figure out the number of times 720163 can be divided by 9.

Moving on to step 1:
7 divided by 9 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 9

Step 2:
72 divided by 9 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 72 from 72 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 9

Advancing to step 3:
When dividing 0 by 9, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 0, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 9

Step 4:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 800.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 9

Step 5:
The number 9 fits into 16 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 8001.0
If we take 9 away from 16, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 9

On to step 6:
73 divided by 9 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 80018.0
Subtracting 72 from 73 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 80018.1
Subtracting 9 from 10 leaves us with 1.
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 8:
The number 9 fits into 10 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 80018.11
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 80018.11, and the remainder is 0.001.
