65078 ÷ 21 
We want to divide 65078 by 21.

Step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

Moving on to step 2:
65 divided by 21 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 2 after subtracting 63 from 65.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 21

Going ahead to step 3:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 21

Step 4:
21 goes into 207 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Deduct 189 from 207 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 21

On to step 5:
21 goes into 188 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3098.0
The remainder is 20 after subtracting 168 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 6:
When dividing 200 by 21, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3098.9
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3098.95
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 3098.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3098.9523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 3098.95238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
21 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3098.95238
Subtract 0 from 20 to 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.

Advancing to step 12:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3098.9523809
If we take 189 away from 200, we end up 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.

Let's proceed to step 13:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3098.95238095
Subtract 105 from 110 to 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.

In conclusion, the division gives 3098.95238095 with a balance of 5e-09.
