21238 ÷ 6 
We want to figure out the number of times 21238 can be divided by 6.

Moving on to step 1:
2 divided by 6 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 6

On to step 2:
21 divided by 6 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 18 away from 21, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 6

Step 3:
If we divide 32 by 6, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 30 from 32 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 6

Let's proceed to step 4:
23 divided by 6 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 353.0
The remainder is 5 after subtracting 18 from 23.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 6

Moving on to step 5:
When dividing 58 by 6, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 3539.0
The remainder is 4 after subtracting 54 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
6 goes into 40 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3539.6
Subtracting 36 from 40 leaves us 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 7:
When dividing 40 by 6, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3539.66
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 3539.66, and the remainder is 0.004.
