We look at the division of 19993 by 75 
Let's see how many times 75 fits into 19993.

Advancing to step 1:
75 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 75

Step 2:
75 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 75

Let's proceed to step 3:
If we divide 199 by 75, we get 2 and a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 150 from 199 leaves us with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 75

Step 4:
When dividing 499 by 75, we get 6 with a remainder of 49.
The next digit of our result is 6. 
Result so far: 26.0
If we take 450 away from 499, we end up with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 75

Moving on to step 5:
75 can be fit into 493 6 times, resulting in a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.0
The remainder is 43 after subtracting 450 from 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 6:
The number 75 fits into 430 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 266.5
Subtracting 375 from 430 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
75 can be fit into 550 7 times, resulting in a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 266.57
If we subtract 525 from 550, 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 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 266.573
Subtract 225 from 250 to 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:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 266.5733
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 266.5733, with a leftover of 0.00025.
