We look at the division of 38089677 by 28 
The aim is to understand the frequency of 28 in 38089677.

Advancing to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 28

Step 2:
When dividing 38 by 28, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 28 from 38 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 28

Advancing to step 3:
If we divide 100 by 28, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 84 from 100 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 28

Going ahead to step 4:
When dividing 168 by 28, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we take 168 away from 168, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 28

Step 5:
9 divided by 28 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 1360.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 28

On to step 6:
28 goes into 96 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 13603.0
The remainder is 12 after subtracting 84 from 96.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 28

Step 7:
127 divided by 28 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 136034.0
If we subtract 112 from 127, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 28

Let's proceed to step 8:
When dividing 157 by 28, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1360345.0
The remainder is 17 after subtracting 140 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
If we divide 170 by 28, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1360345.6
Subtract 168 from 170 to get 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 10:
28 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1360345.6
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.

Advancing to step 11:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1360345.607
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 12:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1360345.6071
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.

Let's proceed to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1360345.60714
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 14:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1360345.607142
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.

Step 15:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 1360345.6071428
If we subtract 224 from 240, we get 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 16:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1360345.60714285
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.

After the division, we end up with 1360345.60714285 and a remainder of 2e-08.
