423584 ÷ 10 
Our goal is to divide 423584 by 10.

Step 1:
10 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 10

Step 2:
42 divided by 10 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 2 after subtracting 40 from 42.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 10

Going ahead to step 3:
10 goes into 23 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 20 from 23, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 10

On to step 4:
10 goes into 35 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 423.0
The remainder is 5 after subtracting 30 from 35.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 10

Going ahead to step 5:
When dividing 58 by 10, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 4235.0
If we subtract 50 from 58, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 10

Let's proceed to step 6:
10 can be fit into 84 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 42358.0
If we subtract 80 from 84, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
10 goes into 40 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 42358.4
The remainder is 0 after subtracting 40 from 40.
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 8:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42358.4
If we subtract 0 from 0, 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.

Moving on to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42358.4
Subtract 0 from 0 to 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.

The final result is 42358.4 with a remainder of 0.0.
