333163 ÷ 21 
Let's see how many times 21 fits into 333163.

Moving on to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

Step 2:
The number 21 fits into 33 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 33 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 21

Advancing to step 3:
21 goes into 123 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 105 from 123 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 21

Going ahead to step 4:
The number 21 fits into 181 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 158.0
If we subtract 168 from 181, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Advancing to step 5:
21 goes into 136 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1586.0
Deduct 126 from 136 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 21

On to step 6:
When dividing 103 by 21, we get 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 15864.0
The remainder is 19 after subtracting 84 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 15864.9
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15864.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15864.904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 15864.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 15864.90476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 15864.904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 15864.9047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15864.9047619
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 15864.9047619 with a balance of 1e-08.
