We look at the division of 447734 by 21 
Let's see how many times 21 fits into 447734.

Advancing to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 21

On to step 2:
When dividing 44 by 21, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 44 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

On to step 3:
The number 21 fits into 27 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 21 from 27 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 21

On to step 4:
21 goes into 67 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we subtract 63 from 67, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 21

Going ahead to step 5:
When dividing 43 by 21, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2132.0
If we subtract 42 from 43, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 21

Moving on to step 6:
21 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 21320.0
Deduct 0 from 14 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 21320.6
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
21 can be fit into 140 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 21320.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 21320.66 and a remainder of 0.014.
