We look at the division of 28867425 by 684 
The aim is to understand the frequency of 684 in 28867425.

Let's proceed to step 1:
684 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 684

Moving on to step 2:
The number 684 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 684

Moving on to step 3:
684 can be fit into 288 0 times, resulting in a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Bring next digit (6) of the dividend behind the 288 and repeat the process: 2886 / 684

Moving on to step 4:
684 can be fit into 2886 4 times, resulting in a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2736 away from 2886, we end up with 150.
Take the next digit (7) from the dividend and append it to 150, then repeat: 1507 / 684

Moving on to step 5:
684 can be fit into 1507 2 times, resulting in a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 1368 from 1507 to get 139.
Bring next digit (4) of the dividend behind the 139 and repeat the process: 1394 / 684

Going ahead to step 6:
If we divide 1394 by 684, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 422.0
Subtract 1368 from 1394 to get 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 684

Step 7:
684 can be fit into 262 0 times, resulting in a remainder of 262.
Put 0 as the next digit of the answer. 
Result so far: 4220.0
Subtract 0 from 262 to get 262.
Bring next digit (5) of the dividend behind the 262 and repeat the process: 2625 / 684

Moving on to step 8:
684 goes into 2625 3 times with a remainder of 573.
The next digit of our result is 3. 
Result so far: 42203.0
Subtracting 2052 from 2625 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 9:
5730 divided by 684 is 8 with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 42203.8
Subtracting 5472 from 5730 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 10:
684 can be fit into 2580 3 times, resulting in a remainder of 528.
The number 3 becomes the next digit in our result. 
Result so far: 42203.83
Subtract 2052 from 2580 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 11:
The number 684 fits into 5280 7 times, leaving a remainder of 492.
Use 7 as the next digit of our solution. 
Result so far: 42203.837
Subtract 4788 from 5280 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 12:
684 can be fit into 4920 7 times, resulting in a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 42203.8377
Subtract 4788 from 4920 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 42203.8377 with a remaining 0.00132.
