We look at the division of 28167 by 39 
The aim is to understand the frequency of 39 in 28167.

Step 1:
2 divided by 39 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 39

Advancing to step 2:
39 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 39

Going ahead to step 3:
39 can be fit into 281 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 273 from 281 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 39

Step 4:
39 goes into 86 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 78 from 86, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 39

Let's proceed to step 5:
39 can be fit into 87 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 722.0
The remainder is 9 after subtracting 78 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 6:
When dividing 90 by 39, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 722.2
If we subtract 78 from 90, we get 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 7:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 722.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 39 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 722.23
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 39, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 722.2307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
39 can be fit into 270 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 722.23076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 39, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 722.230769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
When dividing 90 by 39, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 722.2307692
Deduct 78 from 90 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.

On to step 13:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 722.23076923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 722.23076923 with a remaining 3e-09.
