We're dividing 409503 by 10 
We want to divide 409503 by 10.

Advancing to step 1:
10 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 10

Let's proceed to step 2:
If we divide 40 by 10, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 40 from 40.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 10

Let's proceed to step 3:
The number 10 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 10

Moving on to step 4:
95 divided by 10 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
If we subtract 90 from 95, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 10

Advancing to step 5:
If we divide 50 by 10, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4095.0
Deduct 50 from 50 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 10

Let's proceed to step 6:
10 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 40950.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
10 goes into 30 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 40950.3
Deduct 30 from 30 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.

Going ahead to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40950.3
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.

Let's proceed to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40950.3
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.

After the division, we end up with 40950.3 and a remainder of 0.0.
