We're dividing 2604075 by 286 
The aim is to understand the frequency of 286 in 2604075.

Step 1:
2 divided by 286 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 286

Step 2:
26 divided by 286 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 286

Advancing to step 3:
260 divided by 286 is 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 260, we get 260.
Fetch the next digit (4) from the dividend, attach it to 260 and continue: 2604 / 286

Going ahead to step 4:
2604 divided by 286 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 2574 from 2604 leaves us with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 286

Advancing to step 5:
286 goes into 300 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 286 from 300 leaves us with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 286

Let's proceed to step 6:
If we divide 147 by 286, we get 0 and a remainder of 147.
Write down 0 as next digit of the result. 
Result so far: 910.0
Deduct 0 from 147 and we're left with 147.
Append the next digit (5) from the dividend to 147 and continue with: 1475 / 286

Moving on to step 7:
286 goes into 1475 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 9105.0
If we take 1430 away from 1475, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
If we divide 450 by 286, we get 1 and a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 9105.1
Deduct 286 from 450 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 9:
The number 286 fits into 1640 5 times, leaving a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 9105.15
Subtracting 1430 from 1640 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
If we divide 2100 by 286, we get 7 and a remainder of 98.
The next digit of our result is 7. 
Result so far: 9105.157
If we take 2002 away from 2100, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
286 can be fit into 980 3 times, resulting in a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 9105.1573
Subtract 858 from 980 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 12:
When dividing 1220 by 286, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 9105.15734
Subtracting 1144 from 1220 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
When dividing 760 by 286, we get 2 with a remainder of 188.
The next digit of our result is 2. 
Result so far: 9105.157342
Subtract 572 from 760 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 14:
If we divide 1880 by 286, we get 6 and a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 9105.1573426
Deduct 1716 from 1880 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
The number 286 fits into 1640 5 times, leaving a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 9105.15734265
Subtracting 1430 from 1640 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 9105.15734265 with a balance of 2.1e-07.
