We look at the division of 590744 by 21 
We want to divide 590744 by 21.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Let's proceed to step 2:
When dividing 59 by 21, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 59, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 21

Going ahead to step 3:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 168 from 170, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Going ahead to step 4:
If we divide 27 by 21, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
If we take 21 away from 27, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 21

Moving on to step 5:
21 goes into 64 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 2813.0
If we take 63 away from 64, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Let's proceed to step 6:
When dividing 14 by 21, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 28130.0
The remainder is 14 after subtracting 0 from 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.
The number 6 becomes the next digit in our result. 
Result so far: 28130.6
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.

Going ahead to step 8:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 28130.66
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.

Our division results in 28130.66 with a remaining 0.014.
