Let's divide 189821 by 3
Our goal is to divide 189821 by 3.

Advancing to step 1:
1 divided by 3 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Going ahead to step 2:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Advancing to step 3:
3 goes into 9 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Step 4:
3 goes into 8 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 632.0
If we subtract 6 from 8, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Let's proceed to step 5:
3 goes into 22 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 6327.0
Subtract 21 from 22 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Advancing to step 6:
11 divided by 3 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 63273.0
Deduct 9 from 11 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 63273.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 63273.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 63273.66 with a remainder of 0.002.
