We look at the division of 523560 by 9 
We want to figure out the number of times 523560 can be divided by 9.

Step 1:
If we divide 5 by 9, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 9

Let's proceed to step 2:
If we divide 52 by 9, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 45 from 52 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 9

Step 3:
9 can be fit into 73 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 72 from 73, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 9

Step 4:
The number 9 fits into 15 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 581.0
Subtracting 9 from 15 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 9

Step 5:
9 can be fit into 66 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5817.0
Deduct 63 from 66 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Advancing to step 6:
When dividing 30 by 9, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 58173.0
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
9 goes into 30 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 58173.3
Deduct 27 from 30 and we're left with 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 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 58173.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 58173.33 and a remainder of 0.003.
