We're dividing 780394 by 75 
We're looking to find how many times 75 goes into 780394.

Let's proceed to step 1:
The number 75 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 75

Step 2:
75 goes into 78 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 75 from 78 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 75

Going ahead to step 3:
75 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 75

Moving on to step 4:
When dividing 303 by 75, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 300 from 303, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 75

Advancing to step 5:
When dividing 39 by 75, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 1040.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 75

Going ahead to step 6:
394 divided by 75 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 10405.0
Deduct 375 from 394 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
75 can be fit into 190 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 10405.2
If we take 150 away from 190, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
75 goes into 400 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10405.25
If we subtract 375 from 400, 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.

Let's proceed to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 10405.253
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.

Going ahead to step 10:
75 goes into 250 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 10405.2533
Deduct 225 from 250 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.

In conclusion, the division gives 10405.2533 with a balance of 0.00025.
