Let's divide 509854 by 28
Let's see how many times 28 fits into 509854.

Going ahead to step 1:
When dividing 5 by 28, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 28

Step 2:
When dividing 50 by 28, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 28 from 50 and we're left with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 28

Moving on to step 3:
When dividing 229 by 28, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 224 from 229 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 28

Let's proceed to step 4:
28 can be fit into 58 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 182.0
The remainder is 2 after subtracting 56 from 58.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 28

Step 5:
The number 28 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 1820.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 28

Step 6:
If we divide 254 by 28, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 18209.0
Subtract 252 from 254 to 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.

Step 7:
The number 28 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18209.0
If we subtract 0 from 20, we 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 8:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 18209.07
The remainder is 4 after subtracting 196 from 200.
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 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 18209.071
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 18209.0714
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.

On to step 11:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 18209.07142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 18209.071428
If we subtract 224 from 240, we 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.

Let's proceed to step 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 18209.0714285
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.

Advancing to step 14:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 18209.07142857
Deduct 196 from 200 and we're left 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.

The final result is 18209.07142857 with a remainder of 4e-09.
