48078 divided by 21 
We want to divide 48078 by 21.

Moving on to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 21

On to step 2:
48 divided by 21 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 42 away from 48, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 21

Advancing to step 3:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 42 from 60, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 21

Let's proceed to step 4:
The number 21 fits into 187 8 times, leaving a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 228.0
The remainder is 19 after subtracting 168 from 187.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 21

Going ahead to step 5:
If we divide 198 by 21, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 2289.0
Subtracting 189 from 198 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.

Advancing to step 6:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2289.4
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2289.42
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2289.428
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.

Going ahead to step 9:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2289.4285
Subtracting 105 from 120 leaves us 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.

Moving on to step 10:
When dividing 150 by 21, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 2289.42857
If we take 147 away from 150, we end up 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.

Advancing to step 11:
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: 2289.428571
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.

Moving on to step 12:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 2289.4285714
If we subtract 84 from 90, we get 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 13:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2289.42857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 2289.42857142 with a balance of 1.8e-08.
