239027 divided by 21 
We're looking to find how many times 21 goes into 239027.

Going ahead to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 21

Let's proceed to step 2:
21 can be fit into 23 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 21 from 23.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

On to step 3:
21 can be fit into 29 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 21 from 29 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 21

Let's proceed to step 4:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 113.0
Subtract 63 from 80 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 21

Let's proceed to step 5:
The number 21 fits into 172 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1138.0
Subtracting 168 from 172 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

Step 6:
21 goes into 47 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 11382.0
If we subtract 42 from 47, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11382.2
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 11382.23
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 11382.238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11382.238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 11382.23809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
21 goes into 110 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11382.238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11382.2380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 11382.23809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 11382.23809523 and a remainder of 1.7e-08.
