Let's divide 21278886 by 516
Our goal is to divide 21278886 by 516.

Advancing to step 1:
516 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 516

Going ahead to step 2:
The number 516 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 516

Let's proceed to step 3:
212 divided by 516 is 0 with a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Fetch the next digit (7) from the dividend, attach it to 212 and continue: 2127 / 516

Moving on to step 4:
516 goes into 2127 4 times with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 63 after subtracting 2064 from 2127.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 516

Going ahead to step 5:
516 can be fit into 638 1 times, resulting in a remainder of 122.
The next digit of our result is 1. 
Result so far: 41.0
If we take 516 away from 638, we end up with 122.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 516

Step 6:
1228 divided by 516 is 2 with a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 412.0
Deduct 1032 from 1228 and we're left with 196.
Grab the next digit (8) from the dividend, add it to 196, then carry on: 1968 / 516

Advancing to step 7:
516 goes into 1968 3 times with a remainder of 420.
The next digit of our result is 3. 
Result so far: 4123.0
Subtracting 1548 from 1968 leaves us with 420.
Fetch the next digit (6) from the dividend, attach it to 420 and continue: 4206 / 516

Step 8:
516 can be fit into 4206 8 times, resulting in a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 41238.0
Subtracting 4128 from 4206 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
516 goes into 780 1 times with a remainder of 264.
The next digit of our result is 1. 
Result so far: 41238.1
If we take 516 away from 780, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
516 goes into 2640 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 41238.15
Subtract 2580 from 2640 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
516 can be fit into 600 1 times, resulting in a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 41238.151
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
The number 516 fits into 840 1 times, leaving a remainder of 324.
The next digit of our result is 1. 
Result so far: 41238.1511
Subtracting 516 from 840 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 41238.1511 with a balance of 0.00324.
