Let's divide 749519 by 28
The aim is to understand the frequency of 28 in 749519.

Advancing to step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 28

Advancing to step 2:
If we divide 74 by 28, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 56 from 74 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 28

Moving on to step 3:
28 goes into 189 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 21 after subtracting 168 from 189.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 28

Step 4:
The number 28 fits into 215 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 267.0
If we take 196 away from 215, we end up with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 28

Step 5:
28 goes into 191 6 times with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 2676.0
If we subtract 168 from 191, we get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 28

On to step 6:
239 divided by 28 is 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 26768.0
The remainder is 15 after subtracting 224 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 28 fits into 150 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 26768.5
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 28, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 26768.53
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 26768.535
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.

Step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 26768.5357
Subtract 196 from 200 to 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.

Going ahead to step 11:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 26768.53571
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:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 26768.535714
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 13:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 26768.5357142
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.

Advancing to step 14:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 26768.53571428
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.

Our division results in 26768.53571428 with a remaining 1.6e-08.
