449465 divided by 21 
Let's see how many times 21 fits into 449465.

Let's proceed to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Step 2:
21 can be fit into 44 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 42 from 44 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 21

Step 3:
21 goes into 29 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 8 after subtracting 21 from 29.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 21

Let's proceed to step 4:
84 divided by 21 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 214.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 21

Let's proceed to step 5:
If we divide 6 by 21, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 2140.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 21

On to step 6:
If we divide 65 by 21, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 21403.0
Subtracting 63 from 65 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 21 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 21403.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 21403.09
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
If we divide 110 by 21, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 21403.095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 21403.0952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 21403.09523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 21403.095238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21403.095238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 21403.09523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 21403.09523809 with a remaining 1.1e-08.
