51012080 ÷ 28 
Our goal is to divide 51012080 by 28.

Step 1:
28 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 28

Moving on to step 2:
The number 28 fits into 51 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 28 from 51 and we're left with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 28

Step 3:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 224 from 230 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 28

Step 4:
If we divide 61 by 28, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 182.0
If we take 56 away from 61, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 28

On to step 5:
If we divide 52 by 28, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1821.0
If we take 28 away from 52, we end up with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 28

On to step 6:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18218.0
Subtract 224 from 240 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 28

Going ahead to step 7:
If we divide 168 by 28, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 182186.0
Deduct 168 from 168 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 28

Advancing to step 8:
When dividing 0 by 28, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1821860.0
If we take 0 away from 0, we end up 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.

On to step 9:
When dividing 0 by 28, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1821860.0
If we take 0 away from 0, we end up 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.

Going ahead to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1821860.0
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.

In conclusion, the division gives 1821860.0 with a balance of 0.0.
