We look at the division of 461005 by 21 
Let's see how many times 21 fits into 461005.

Moving on to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 21

Moving on to step 2:
If we divide 46 by 21, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 42 from 46 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 21

Moving on to step 3:
The number 21 fits into 41 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 21 from 41 to get 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 21

Step 4:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Subtracting 189 from 200 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 21

On to step 5:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2195.0
Subtract 105 from 110 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 21

Let's proceed to step 6:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 21952.0
The remainder is 13 after subtracting 42 from 55.
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 7:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 21952.6
Deduct 126 from 130 and we're left 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.

Advancing to step 8:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 21952.61
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 21952.619
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.

Going ahead to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21952.619
If we subtract 0 from 10, we 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.

Advancing to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 21952.61904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 21952.619047
Subtract 147 from 160 to 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 13:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 21952.6190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 21952.61904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 21952.61904761 with a remainder of 1.9e-08.
