We look at the division of 65410 by 28 
The aim is to understand the frequency of 28 in 65410.

On to step 1:
28 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 28

Advancing to step 2:
When dividing 65 by 28, we get 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 9 after subtracting 56 from 65.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 28

Let's proceed to step 3:
When dividing 94 by 28, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 28

Step 4:
28 goes into 101 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we take 84 away from 101, we end up with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 28

Step 5:
The number 28 fits into 170 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2336.0
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
When dividing 20 by 28, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2336.0
If we take 0 away from 20, 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.

Going ahead to step 7:
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: 2336.07
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.

Let's proceed to step 8:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 2336.071
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.

Advancing to step 9:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2336.0714
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.

Moving on to step 10:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2336.07142
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 11:
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: 2336.071428
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.

Step 12:
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: 2336.0714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 2336.07142857
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.

The final result is 2336.07142857 with a remainder of 4e-09.
