We divide 650487 by 28
The aim is to understand the frequency of 28 in 650487.

Advancing to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 28

On to step 2:
When dividing 65 by 28, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 56 from 65 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 28

Step 3:
28 goes into 90 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 84 from 90 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 28

Going ahead to step 4:
The number 28 fits into 64 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 232.0
The remainder is 8 after subtracting 56 from 64.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 28

On to step 5:
88 divided by 28 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2323.0
Deduct 84 from 88 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 28

Advancing to step 6:
When dividing 47 by 28, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 23231.0
If we take 28 away from 47, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
28 goes into 190 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 23231.6
If we take 168 away from 190, we end up with 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:
When dividing 220 by 28, we get 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 23231.67
The remainder is 24 after subtracting 196 from 220.
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 9:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 23231.678
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.

Advancing to step 10:
If we divide 160 by 28, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 23231.6785
If we take 140 away from 160, we end up 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.

Moving on to step 11:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 23231.67857
If we take 196 away from 200, we end up 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.

Let's proceed to step 12:
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: 23231.678571
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.

Step 13:
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: 23231.6785714
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.

Step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 23231.67857142
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.

Our division results in 23231.67857142 with a remaining 2.4e-08.
