We look at the division of 844277 by 21 
We're looking to find how many times 21 goes into 844277.

Advancing to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 21

Let's proceed to step 2:
When dividing 84 by 21, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 84 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 21

Advancing to step 3:
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: 40.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 21

Going ahead to step 4:
The number 21 fits into 42 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtracting 42 from 42 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 21

On to step 5:
21 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 4020.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 21

Moving on to step 6:
The number 21 fits into 77 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 40203.0
The remainder is 14 after subtracting 63 from 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 40203.6
If we take 126 away from 140, we end up 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.

Step 8:
21 goes into 140 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 40203.66
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 40203.66 with a balance of 0.014.
