We're dividing 750405 by 10 
We're looking to find how many times 10 goes into 750405.

Let's proceed to step 1:
The number 10 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 10

Going ahead to step 2:
75 divided by 10 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 70 from 75 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 10

On to step 3:
When dividing 50 by 10, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 50 from 50 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 10

Step 4:
10 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 750.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 10

Moving on to step 5:
The number 10 fits into 40 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 7504.0
Subtract 40 from 40 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 10

Moving on to step 6:
The number 10 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 75040.0
Subtract 0 from 5 to 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.

Let's proceed to step 7:
10 goes into 50 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 75040.5
Subtracting 50 from 50 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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 75040.5
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.

Moving on to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 75040.5
Subtracting 0 from 0 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.

The final result is 75040.5 with a remainder of 0.0.
