64783 ÷ 28 
The aim is to understand the frequency of 28 in 64783.

Moving on to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 28

Step 2:
When dividing 64 by 28, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 56 from 64, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 28

Moving on to step 3:
87 divided by 28 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 84 from 87 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 28

On to step 4:
The number 28 fits into 38 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 231.0
Subtracting 28 from 38 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 28

On to step 5:
The number 28 fits into 103 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 2313.0
Deduct 84 from 103 and we're left 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.

Let's proceed to step 6:
The number 28 fits into 190 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 2313.6
The remainder is 22 after subtracting 168 from 190.
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 7:
220 divided by 28 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 2313.67
If we take 196 away from 220, we end up 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 8:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 2313.678
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.

Advancing to step 9:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2313.6785
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.

Step 10:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 2313.67857
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.

Going ahead to step 11:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 2313.678571
Deduct 28 from 40 and we're left with 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 12:
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: 2313.6785714
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.

On to step 13:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2313.67857142
Subtract 56 from 80 to 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.

Our division results in 2313.67857142 with a remaining 2.4e-08.
