We look at the division of 664571 by 28 
We want to figure out the number of times 664571 can be divided by 28.

Going ahead to step 1:
6 divided by 28 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 28

Moving on to step 2:
If we divide 66 by 28, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 56 away from 66, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 28

Advancing to step 3:
28 goes into 104 3 times with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 84 from 104 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 28

Advancing to step 4:
205 divided by 28 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
Subtracting 196 from 205 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 28

Advancing to step 5:
28 goes into 97 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 2373.0
Subtracting 84 from 97 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 28

Let's proceed to step 6:
28 can be fit into 131 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 23734.0
If we subtract 112 from 131, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
28 can be fit into 190 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 23734.6
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
28 goes into 220 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 23734.67
Deduct 196 from 220 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.

Let's proceed to step 9:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 23734.678
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.

Step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 23734.6785
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.

Let's proceed to step 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 23734.67857
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.

Let's proceed to step 12:
40 divided by 28 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 23734.678571
If we subtract 28 from 40, we 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.

Let's proceed to step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 23734.6785714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 23734.67857142
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.

After the division, we end up with 23734.67857142 and a remainder of 2.4e-08.
