We're dividing 145339 by 28 
The aim is to understand the frequency of 28 in 145339.

Going ahead to step 1:
28 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 28

Step 2:
28 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 28

Step 3:
If we divide 145 by 28, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 140 from 145 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 28

Going ahead to step 4:
28 can be fit into 53 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 25 after subtracting 28 from 53.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 28

Step 5:
28 can be fit into 253 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
The remainder is 1 after subtracting 252 from 253.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 28

Step 6:
28 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 5190.0
Deduct 0 from 19 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.

Going ahead to step 7:
28 can be fit into 190 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 5190.6
If we subtract 168 from 190, we 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.

Moving on to step 8:
When dividing 220 by 28, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 5190.67
Subtract 196 from 220 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.

On to step 9:
240 divided by 28 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5190.678
Subtracting 224 from 240 leaves us 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 10:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 5190.6785
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:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 5190.67857
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.

Step 12:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 5190.678571
If we take 28 away from 40, we end up 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 13:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 5190.6785714
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:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5190.67857142
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 5190.67857142 with a remaining 2.4e-08.
