We look at the division of 738739 by 28 
The aim is to understand the frequency of 28 in 738739.

Moving on to step 1:
28 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 28

Moving on to step 2:
28 can be fit into 73 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 56 from 73 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 28

On to step 3:
The number 28 fits into 178 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 10 after subtracting 168 from 178.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 28

Step 4:
28 goes into 107 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 263.0
If we take 84 away from 107, we end up with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 28

Moving on to step 5:
28 goes into 233 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2638.0
The remainder is 9 after subtracting 224 from 233.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 28

Advancing to step 6:
When dividing 99 by 28, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 26383.0
If we take 84 away from 99, we end up with 15.
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:
150 divided by 28 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 26383.5
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
28 goes into 100 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 26383.53
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.

Advancing to step 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 26383.535
Subtract 140 from 160 to 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.

Let's proceed to step 10:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 26383.5357
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.

Step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 26383.53571
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 12:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 26383.535714
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.

Let's proceed 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: 26383.5357142
If we take 56 away from 80, 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.

Going ahead to step 14:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 26383.53571428
If we take 224 away from 240, we end up 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.

The final outcome is 26383.53571428, with a leftover of 1.6e-08.
