Let's divide 321998 by 75
Let's see how many times 75 fits into 321998.

Going ahead to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 75

Advancing to step 2:
When dividing 32 by 75, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 75

Step 3:
321 divided by 75 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 21 after subtracting 300 from 321.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 75

Advancing to step 4:
75 can be fit into 219 2 times, resulting in a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 150 from 219 and we're left with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 75

Going ahead to step 5:
If we divide 699 by 75, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we take 675 away from 699, we end up with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 75

Let's proceed to step 6:
248 divided by 75 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 4293.0
Deduct 225 from 248 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
230 divided by 75 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 4293.3
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
75 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4293.3
The remainder is 50 after subtracting 0 from 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:
500 divided by 75 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 4293.306
If we take 450 away from 500, we end up 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.

On to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 4293.3066
Subtract 450 from 500 to 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.

The final outcome is 4293.3066, with a leftover of 0.0005.
