We divide 423308 by 10
We're looking to find how many times 10 goes into 423308.

Advancing to step 1:
If we divide 4 by 10, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 10

On to step 2:
The number 10 fits into 42 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 2 after subtracting 40 from 42.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 10

Let's proceed to step 3:
10 can be fit into 23 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 42.0
If we take 20 away from 23, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 10

Let's proceed to step 4:
10 goes into 33 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 423.0
If we take 30 away from 33, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 10

Going ahead to step 5:
30 divided by 10 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 4233.0
Subtracting 30 from 30 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 10

On to step 6:
If we divide 8 by 10, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 42330.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
10 can be fit into 80 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 42330.8
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42330.8
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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42330.8
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.

After the division, we end up with 42330.8 and a remainder of 0.0.
