466305 ÷ 21 
Our goal is to divide 466305 by 21.

Step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 21

Step 2:
21 can be fit into 46 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 42 from 46.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 21

Moving on to step 3:
21 goes into 46 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 4 after subtracting 42 from 46.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 21

Let's proceed to step 4:
21 can be fit into 43 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
The remainder is 1 after subtracting 42 from 43.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 21

Step 5:
21 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2220.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 21

Going ahead to step 6:
21 goes into 105 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22205.0
Deduct 105 from 105 and we're left 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.

Step 7:
0 divided by 21 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22205.0
Subtracting 0 from 0 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.

Advancing to step 8:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22205.0
Subtracting 0 from 0 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.

In conclusion, the division gives 22205.0 with a balance of 0.0.
