Let's divide 865503 by 28
We want to figure out the number of times 865503 can be divided by 28.

Going ahead to step 1:
28 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 28

On to step 2:
28 goes into 86 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 84 from 86 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 28

On to step 3:
28 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 28

Moving on to step 4:
255 divided by 28 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
Deduct 252 from 255 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 28

Let's proceed to step 5:
28 goes into 30 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 3091.0
Subtract 28 from 30 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 28

Step 6:
28 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 30910.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
28 goes into 230 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 30910.8
If we take 224 away from 230, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 28, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 30910.82
If we subtract 56 from 60, 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.

Step 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 30910.821
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.

Let's proceed to step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 30910.8214
If we subtract 112 from 120, we get 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:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 30910.82142
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.

Moving on to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 30910.821428
Deduct 224 from 240 and we're left with 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:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 30910.8214285
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.

On to step 14:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 30910.82142857
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.

Our division results in 30910.82142857 with a remaining 4e-09.
