We look at the division of 28660075 by 684 
The aim is to understand the frequency of 684 in 28660075.

Let's proceed to step 1:
If we divide 2 by 684, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 684

Going ahead to step 2:
When dividing 28 by 684, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 684

Moving on to step 3:
The number 684 fits into 286 0 times, leaving a remainder of 286.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 286 after subtracting 0 from 286.
Fetch the next digit (6) from the dividend, attach it to 286 and continue: 2866 / 684

Advancing to step 4:
684 goes into 2866 4 times with a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2736 away from 2866, we end up with 130.
Grab the next digit (0) from the dividend, add it to 130, then carry on: 1300 / 684

Advancing to step 5:
When dividing 1300 by 684, we get 1 with a remainder of 616.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 684 from 1300, we get 616.
Include the next digit (0) from the dividend after 616, then repeat: 6160 / 684

Let's proceed to step 6:
If we divide 6160 by 684, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 419.0
The remainder is 4 after subtracting 6156 from 6160.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 684

Going ahead to step 7:
47 divided by 684 is 0 with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 4190.0
If we take 0 away from 47, we end up with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 684

Step 8:
If we divide 475 by 684, we get 0 and a remainder of 475.
The next digit of our result is 0. 
Result so far: 41900.0
If we take 0 away from 475, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 9:
When dividing 4750 by 684, we get 6 with a remainder of 646.
Put 6 as the next digit of the answer. 
Result so far: 41900.6
If we take 4104 away from 4750, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 10:
684 can be fit into 6460 9 times, resulting in a remainder of 304.
Put 9 as the next digit of the answer. 
Result so far: 41900.69
Subtract 6156 from 6460 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 11:
3040 divided by 684 is 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 41900.694
Subtract 2736 from 3040 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 12:
684 can be fit into 3040 4 times, resulting in a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 41900.6944
The remainder is 304 after subtracting 2736 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 41900.6944 with a remaining 0.00304.
