We look at the division of 51480 by 28 
We want to divide 51480 by 28.

On to step 1:
28 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 28

Step 2:
When dividing 51 by 28, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 28 from 51 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 28

Step 3:
28 can be fit into 234 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 224 from 234 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 28

On to step 4:
When dividing 108 by 28, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
The remainder is 24 after subtracting 84 from 108.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 28

Step 5:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1838.0
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 6:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 1838.5
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1838.57
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1838.571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1838.5714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1838.57142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1838.571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1838.5714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1838.57142857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1838.57142857 with a remaining 4e-09.
