We look at the division of 39222940 by 28 
The aim is to understand the frequency of 28 in 39222940.

Advancing to step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 28

Moving on to step 2:
39 divided by 28 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 28 from 39.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 28

Moving on to step 3:
When dividing 112 by 28, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 112 away from 112, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 28

Step 4:
2 divided by 28 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 28

Going ahead to step 5:
28 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 1400.0
Deduct 0 from 22 and we're left with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 28

Step 6:
If we divide 229 by 28, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 14008.0
If we take 224 away from 229, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 28

Going ahead to step 7:
54 divided by 28 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 140081.0
Subtract 28 from 54 to get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 28

Advancing to step 8:
The number 28 fits into 260 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 1400819.0
Subtracting 252 from 260 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.

Going ahead to step 9:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1400819.2
If we subtract 56 from 80, we 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.

Moving on to step 10:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1400819.28
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 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1400819.285
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 12:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 1400819.2857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1400819.28571
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 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1400819.285714
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.

Let's proceed to step 15:
80 divided by 28 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1400819.2857142
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 16:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1400819.28571428
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.

The final result is 1400819.28571428 with a remainder of 1.6e-08.
