Let's divide 588499 by 21
We want to divide 588499 by 21.

Advancing to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

On to step 2:
When dividing 58 by 21, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 58 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 21

Let's proceed to step 3:
168 divided by 21 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 168 from 168 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 21

Let's proceed to step 4:
4 divided by 21 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

Going ahead to step 5:
21 can be fit into 49 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2802.0
The remainder is 7 after subtracting 42 from 49.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 21

Advancing to step 6:
The number 21 fits into 79 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 28023.0
Deduct 63 from 79 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 28023.7
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
21 goes into 130 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 28023.76
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.

Going ahead to step 9:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 28023.761
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.

Let's proceed to step 10:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 28023.7619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 28023.7619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 28023.761904
Subtract 84 from 100 to 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.

Going ahead to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 28023.7619047
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 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 28023.76190476
If we subtract 126 from 130, we 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.

Our division results in 28023.76190476 with a remaining 4e-09.
