28136 divided by 73 
The aim is to understand the frequency of 73 in 28136.

On to step 1:
The number 73 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 73

On to step 2:
73 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 73

Going ahead to step 3:
73 goes into 281 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 219 away from 281, we end up with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 73

Let's proceed to step 4:
73 goes into 623 8 times with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 584 from 623 and we're left with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 73

Advancing to step 5:
396 divided by 73 is 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 385.0
Subtracting 365 from 396 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 6:
When dividing 310 by 73, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 385.4
Deduct 292 from 310 and we're left 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 7:
The number 73 fits into 180 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 385.42
If we subtract 146 from 180, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 73 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 385.424
Deduct 292 from 340 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
480 divided by 73 is 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 385.4246
Deduct 438 from 480 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
73 goes into 420 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 385.42465
If we subtract 365 from 420, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
The number 73 fits into 550 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 385.424657
Subtract 511 from 550 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
If we divide 390 by 73, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 385.4246575
The remainder is 25 after subtracting 365 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
73 can be fit into 250 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 385.42465753
Subtract 219 from 250 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 385.42465753 with a remainder of 3.1e-08.
