We're dividing 459655 by 21 
Our goal is to divide 459655 by 21.

Let's proceed to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 21

Step 2:
21 can be fit into 45 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 45 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

Step 3:
21 goes into 39 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 21 from 39 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 21

Moving on to step 4:
If we divide 186 by 21, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 218.0
Subtracting 168 from 186 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 21

Advancing to step 5:
185 divided by 21 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 2188.0
The remainder is 17 after subtracting 168 from 185.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 21

Going ahead to step 6:
175 divided by 21 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 21888.0
The remainder is 7 after subtracting 168 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 21888.3
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.

Moving on to step 8:
70 divided by 21 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 21888.33
If we take 63 away from 70, we end up 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.

After the division, we end up with 21888.33 and a remainder of 0.007.
