We look at the division of 599334 by 21 
We want to divide 599334 by 21.

Going ahead to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Let's proceed to step 2:
21 goes into 59 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 17 after subtracting 42 from 59.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Moving on to step 3:
The number 21 fits into 179 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 168 from 179 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 21

On to step 4:
21 goes into 113 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 285.0
The remainder is 8 after subtracting 105 from 113.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Going ahead to step 5:
83 divided by 21 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 2853.0
Subtracting 63 from 83 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 21

Advancing to step 6:
When dividing 204 by 21, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 28539.0
The remainder is 15 after subtracting 189 from 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
21 goes into 150 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 28539.7
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 28539.71
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
21 goes into 90 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 28539.714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
If we divide 60 by 21, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 28539.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
When dividing 180 by 21, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 28539.71428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 28539.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 28539.7142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 28539.71428571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 28539.71428571 with a remainder of 9e-09.
