424403 ÷ 10 
Let's see how many times 10 fits into 424403.

Step 1:
The number 10 fits into 4 0 times, leaving 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.
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.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 40 from 42, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 10

Advancing to step 3:
If we divide 24 by 10, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 4 after subtracting 20 from 24.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 10

On to step 4:
If we divide 44 by 10, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 424.0
Deduct 40 from 44 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 10

Going ahead to step 5:
When dividing 40 by 10, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4244.0
If we subtract 40 from 40, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

On to step 6:
When dividing 3 by 10, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 42440.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 10 fits into 30 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 42440.3
Subtracting 30 from 30 leaves us 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.

Going ahead to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42440.3
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.

Step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42440.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 42440.3 with a remaining 0.0.
