We divide 511556 by 28
We want to figure out the number of times 511556 can be divided by 28.

Going ahead to step 1:
5 divided by 28 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 28

Going ahead to step 2:
28 can be fit into 51 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 28 from 51 and we're left with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 28

Moving on to step 3:
If we divide 231 by 28, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 224 from 231 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 28

Advancing to step 4:
If we divide 75 by 28, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtract 56 from 75 to get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 28

Advancing to step 5:
195 divided by 28 is 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 1826.0
If we take 168 away from 195, we end up with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 28

On to step 6:
28 goes into 276 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 18269.0
If we subtract 252 from 276, we get 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 7:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 18269.8
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 8:
28 goes into 160 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 18269.85
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 18269.857
Subtracting 196 from 200 leaves us 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.

Moving on to step 10:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18269.8571
The remainder is 12 after subtracting 28 from 40.
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 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 18269.85714
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.

Let's proceed to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 18269.857142
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.

Going ahead to step 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 18269.8571428
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.

Moving on to step 14:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 18269.85714285
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.

The final result is 18269.85714285 with a remainder of 2e-08.
