423572 ÷ 9 
Let's see how many times 9 fits into 423572.

Step 1:
The number 9 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 9

Step 2:
When dividing 42 by 9, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we take 36 away from 42, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 9

Moving on to step 3:
9 can be fit into 63 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 63 from 63 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 9

Let's proceed to step 4:
5 divided by 9 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 470.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 9

Step 5:
57 divided by 9 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 4706.0
Subtracting 54 from 57 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 9

Let's proceed to step 6:
9 goes into 32 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 47063.0
If we subtract 27 from 32, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 47063.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 9, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 47063.55
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 47063.55, and the remainder is 0.005.
