464338 ÷ 21 
Our goal is to divide 464338 by 21.

Let's proceed to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
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

Going ahead to step 2:
If we divide 46 by 21, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 42 from 46.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 21

On to step 3:
21 goes into 44 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 42 from 44 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 21

Moving on to step 4:
23 divided by 21 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we take 21 away from 23, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 21

Let's proceed to step 5:
21 can be fit into 23 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 2211.0
If we subtract 21 from 23, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 21

Step 6:
28 divided by 21 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 22111.0
Deduct 21 from 28 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
21 goes into 70 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 22111.3
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 21 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 22111.33
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 22111.33 with a balance of 0.007.
