198921 ÷ 75 
We want to divide 198921 by 75.

Let's proceed to step 1:
1 divided by 75 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 75

Advancing to step 2:
75 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 75

Let's proceed to step 3:
75 goes into 198 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 150 from 198 leaves us with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 75

Moving on to step 4:
When dividing 489 by 75, we get 6 with a remainder of 39.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 450 from 489 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 75

Step 5:
75 goes into 392 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
The remainder is 17 after subtracting 375 from 392.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 75

Moving on to step 6:
171 divided by 75 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2652.0
If we subtract 150 from 171, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 75, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 2652.2
The remainder is 60 after subtracting 150 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
The number 75 fits into 600 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 2652.28
Subtracting 600 from 600 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
75 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2652.28
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2652.28
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2652.28 and a remainder of 0.0.
