21341274 ÷ 778 
Our goal is to divide 21341274 by 778.

Going ahead to step 1:
If we divide 2 by 778, we get 0 and 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 / 778

Advancing to step 2:
21 divided by 778 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 778

Going ahead to step 3:
778 goes into 213 0 times with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Include the next digit (4) from the dividend after 213, then repeat: 2134 / 778

Step 4:
If we divide 2134 by 778, we get 2 and a remainder of 578.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 578 after subtracting 1556 from 2134.
Include the next digit (1) from the dividend after 578, then repeat: 5781 / 778

Step 5:
If we divide 5781 by 778, we get 7 and a remainder of 335.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 5446 away from 5781, we end up with 335.
Bring next digit (2) of the dividend behind the 335 and repeat the process: 3352 / 778

Let's proceed to step 6:
778 can be fit into 3352 4 times, resulting in a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Subtract 3112 from 3352 to get 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 778

On to step 7:
When dividing 2407 by 778, we get 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 2743.0
The remainder is 73 after subtracting 2334 from 2407.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 778

Step 8:
The number 778 fits into 734 0 times, leaving a remainder of 734.
Use 0 as the next digit of our solution. 
Result so far: 27430.0
Subtract 0 from 734 to get 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Step 9:
The number 778 fits into 7340 9 times, leaving a remainder of 338.
Write down 9 as next digit of the result. 
Result so far: 27430.9
If we subtract 7002 from 7340, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 10:
If we divide 3380 by 778, we get 4 and a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 27430.94
If we subtract 3112 from 3380, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
778 can be fit into 2680 3 times, resulting in a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 27430.943
Subtracting 2334 from 2680 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 12:
The number 778 fits into 3460 4 times, leaving a remainder of 348.
The next digit of our result is 4. 
Result so far: 27430.9434
The remainder is 348 after subtracting 3112 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 13:
3480 divided by 778 is 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 27430.94344
Subtract 3112 from 3480 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 27430.94344 with a balance of 0.000368.
