We're dividing 423495 by 10 
Let's see how many times 10 fits into 423495.

Moving on to step 1:
4 divided by 10 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 10

Let's proceed to step 2:
If we divide 42 by 10, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 40 away from 42, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 10

Advancing to step 3:
10 can be fit into 23 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 20 from 23 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 10

Let's proceed to step 4:
34 divided by 10 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
If we take 30 away from 34, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 10

Step 5:
If we divide 49 by 10, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4234.0
Subtracting 40 from 49 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 10

Advancing to step 6:
10 goes into 95 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 42349.0
If we subtract 90 from 95, 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.

On to step 7:
When dividing 50 by 10, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42349.5
If we take 50 away from 50, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42349.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42349.5
If we take 0 away from 0, we end up with 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 quotient of the division is 42349.5, and the remainder is 0.0.
