Let's divide 393010 by 75
We're looking to find how many times 75 goes into 393010.

On to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 75

Step 2:
39 divided by 75 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 75

Going ahead to step 3:
The number 75 fits into 393 5 times, leaving a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 375 away from 393, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 75

Moving on to step 4:
The number 75 fits into 180 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 150 away from 180, we end up with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 75

Let's proceed to step 5:
301 divided by 75 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 524.0
Subtract 300 from 301 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 75

Advancing to step 6:
When dividing 10 by 75, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5240.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
75 can be fit into 100 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 5240.1
Deduct 75 from 100 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
If we divide 250 by 75, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 5240.13
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 5240.133
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 5240.133 and a remainder of 0.0025.
