717490 ÷ 9 
We want to figure out the number of times 717490 can be divided by 9.

On to step 1:
9 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
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 9

Step 2:
9 can be fit into 71 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 63 from 71 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 9

Let's proceed to step 3:
When dividing 87 by 9, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 81 away from 87, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 9

Going ahead to step 4:
The number 9 fits into 64 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Subtract 63 from 64 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 9

Step 5:
9 can be fit into 19 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 7972.0
Subtracting 18 from 19 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 9

Moving on to step 6:
9 goes into 10 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 79721.0
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 79721.1
If we subtract 9 from 10, we get 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:
10 divided by 9 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 79721.11
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 79721.11 and a remainder of 0.001.
