We look at the division of 749405 by 75 
We want to figure out the number of times 749405 can be divided by 75.

On to step 1:
7 divided by 75 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 75

Let's proceed to step 2:
The number 75 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 75

Let's proceed to step 3:
749 divided by 75 is 9 with a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 675 from 749, we get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 75

On to step 4:
When dividing 744 by 75, we get 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 675 from 744 to get 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 75

Moving on to step 5:
75 can be fit into 690 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 999.0
The remainder is 15 after subtracting 675 from 690.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 75

Going ahead to step 6:
When dividing 155 by 75, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 9992.0
If we subtract 150 from 155, 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.

Let's proceed to step 7:
75 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9992.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
500 divided by 75 is 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 9992.06
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 9992.066
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 9992.066 and a remainder of 0.005.
