We're dividing 12702546 by 305 
The aim is to understand the frequency of 305 in 12702546.

On to step 1:
305 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 305

Going ahead to step 2:
305 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 305

On to step 3:
When dividing 127 by 305, we get 0 with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Bring next digit (0) of the dividend behind the 127 and repeat the process: 1270 / 305

Moving on to step 4:
The number 305 fits into 1270 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1220 from 1270, we get 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 305

Let's proceed to step 5:
502 divided by 305 is 1 with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 305 from 502 leaves us with 197.
Grab the next digit (5) from the dividend, add it to 197, then carry on: 1975 / 305

Step 6:
When dividing 1975 by 305, we get 6 with a remainder of 145.
Put 6 as the next digit of the answer. 
Result so far: 416.0
Subtracting 1830 from 1975 leaves us with 145.
Include the next digit (4) from the dividend after 145, then repeat: 1454 / 305

Step 7:
305 goes into 1454 4 times with a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 4164.0
The remainder is 234 after subtracting 1220 from 1454.
Take the next digit (6) from the dividend and append it to 234, then repeat: 2346 / 305

On to step 8:
2346 divided by 305 is 7 with a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 41647.0
Deduct 2135 from 2346 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
305 goes into 2110 6 times with a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 41647.6
If we take 1830 away from 2110, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
305 goes into 2800 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 41647.69
Subtract 2745 from 2800 to 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.

Moving on to step 11:
If we divide 550 by 305, we get 1 and a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 41647.691
Deduct 305 from 550 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 12:
If we divide 2450 by 305, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 41647.6918
The remainder is 10 after subtracting 2440 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
305 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 41647.6918
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
If we divide 1000 by 305, we get 3 and a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 41647.691803
If we take 915 away from 1000, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 15:
305 can be fit into 850 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 41647.6918032
Subtract 610 from 850 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 16:
305 can be fit into 2400 7 times, resulting in a remainder of 265.
Use 7 as the next digit of our solution. 
Result so far: 41647.69180327
If we subtract 2135 from 2400, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

After the division, we end up with 41647.69180327 and a remainder of 2.65e-07.
