50778 ÷ 21 
Let's see how many times 21 fits into 50778.

Advancing to step 1:
5 divided by 21 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 21

Step 2:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 42 from 50, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Let's proceed to step 3:
21 can be fit into 87 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 84 from 87 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 21

Advancing to step 4:
21 can be fit into 37 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 241.0
If we take 21 away from 37, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 21

Let's proceed to step 5:
When dividing 168 by 21, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 2418.0
Deduct 168 from 168 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
If we divide 0 by 21, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2418.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
21 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2418.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2418.0 with a balance of 0.0.
