Let's divide 21199804 by 75
Our goal is to divide 21199804 by 75.

Advancing to step 1:
2 divided by 75 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 75

Let's proceed to step 2:
75 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 75

On to step 3:
The number 75 fits into 211 2 times, leaving a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 150 from 211 leaves us with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 75

Moving on to step 4:
619 divided by 75 is 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 600 from 619, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 75

Going ahead to step 5:
75 can be fit into 199 2 times, resulting in a remainder of 49.
The next digit of our result is 2. 
Result so far: 282.0
Deduct 150 from 199 and we're left with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 75

Moving on to step 6:
When dividing 498 by 75, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 2826.0
Subtract 450 from 498 to get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 75

Advancing to step 7:
75 can be fit into 480 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 28266.0
If we take 450 away from 480, we end up with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 75

Moving on to step 8:
304 divided by 75 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 282664.0
The remainder is 4 after subtracting 300 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 75, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 282664.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 75 fits into 400 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 282664.05
The remainder is 25 after subtracting 375 from 400.
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 11:
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: 282664.053
If we take 225 away from 250, we end up 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 12:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 282664.0533
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.

The final result is 282664.0533 with a remainder of 0.00025.
