21068 ÷ 48 
We want to figure out the number of times 21068 can be divided by 48.

Step 1:
When dividing 2 by 48, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 48

Step 2:
If we divide 21 by 48, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 48

Advancing to step 3:
When dividing 210 by 48, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 18 after subtracting 192 from 210.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 48

Going ahead to step 4:
48 can be fit into 186 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 144 away from 186, we end up with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 48

On to step 5:
48 can be fit into 428 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
The remainder is 44 after subtracting 384 from 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 6:
440 divided by 48 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 438.9
Subtract 432 from 440 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.

On to step 7:
80 divided by 48 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 438.91
Subtracting 48 from 80 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 438.916
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 48, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 438.9166
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 438.9166, and the remainder is 0.00032.
