We're dividing 511139 by 28 
We want to figure out the number of times 511139 can be divided by 28.

Step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 28

Step 2:
28 goes into 51 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 28 from 51 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 28

Let's proceed to step 3:
231 divided by 28 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 224 from 231 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 28

On to step 4:
71 divided by 28 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtract 56 from 71 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 28

Advancing to step 5:
28 goes into 153 5 times with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 1825.0
Subtracting 140 from 153 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 28

Going ahead to step 6:
The number 28 fits into 139 4 times, leaving a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 18254.0
If we subtract 112 from 139, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 28, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 18254.9
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 28 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 18254.96
Subtract 168 from 180 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.

Going ahead to step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 18254.964
Deduct 112 from 120 and we're left 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.

Going ahead to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 18254.9642
Subtracting 56 from 80 leaves us 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.

Let's proceed to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 18254.96428
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.

Advancing to step 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 18254.964285
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.

Going ahead to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 18254.9642857
If we subtract 196 from 200, we 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.

Let's proceed to step 14:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 18254.96428571
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.

Our division results in 18254.96428571 with a remaining 1.2e-08.
