Let's divide 186913 by 28
The aim is to understand the frequency of 28 in 186913.

Advancing to step 1:
If we divide 1 by 28, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 28

Advancing to step 2:
18 divided by 28 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 28

Going ahead to step 3:
186 divided by 28 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 6.0
If we take 168 away from 186, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 28

Advancing to step 4:
28 goes into 189 6 times with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 168 away from 189, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 28

Moving on to step 5:
If we divide 211 by 28, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 667.0
The remainder is 15 after subtracting 196 from 211.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 28

On to step 6:
28 can be fit into 153 5 times, resulting in a remainder of 13.
The next digit of our result is 5. 
Result so far: 6675.0
If we take 140 away from 153, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 28 fits into 130 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 6675.4
Subtracting 112 from 130 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 28, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6675.46
Subtract 168 from 180 to 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.

Moving on to step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 6675.464
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 6675.4642
Subtract 56 from 80 to 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 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6675.46428
Subtract 224 from 240 to 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.

Advancing to step 12:
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: 6675.464285
Deduct 140 from 160 and we're left 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.

Going ahead to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 6675.4642857
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.

Step 14:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 6675.46428571
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.

Our division results in 6675.46428571 with a remaining 1.2e-08.
