28041630 divided by 304 
The aim is to understand the frequency of 304 in 28041630.

Moving on to step 1:
304 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 304

Moving on to step 2:
304 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 304

Moving on to step 3:
When dividing 280 by 304, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 280 leaves us with 280.
Take the next digit (4) from the dividend and append it to 280, then repeat: 2804 / 304

Advancing to step 4:
304 can be fit into 2804 9 times, resulting in a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 2736 from 2804 and we're left with 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 304

Moving on to step 5:
The number 304 fits into 681 2 times, leaving a remainder of 73.
The next digit of our result is 2. 
Result so far: 92.0
If we take 608 away from 681, we end up with 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 304

Advancing to step 6:
If we divide 736 by 304, we get 2 and a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 922.0
Subtract 608 from 736 to get 128.
Bring next digit (3) of the dividend behind the 128 and repeat the process: 1283 / 304

Advancing to step 7:
304 goes into 1283 4 times with a remainder of 67.
The next digit of our result is 4. 
Result so far: 9224.0
Subtract 1216 from 1283 to get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 304

On to step 8:
304 goes into 670 2 times with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 92242.0
If we subtract 608 from 670, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
304 can be fit into 620 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 92242.2
If we subtract 608 from 620, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 304 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 92242.2
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
When dividing 1200 by 304, we get 3 with a remainder of 288.
The next digit of our result is 3. 
Result so far: 92242.203
The remainder is 288 after subtracting 912 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
304 can be fit into 2880 9 times, resulting in a remainder of 144.
The next digit of our result is 9. 
Result so far: 92242.2039
Subtract 2736 from 2880 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
The number 304 fits into 1440 4 times, leaving a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 92242.20394
Subtracting 1216 from 1440 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
The number 304 fits into 2240 7 times, leaving a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 92242.203947
Deduct 2128 from 2240 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
When dividing 1120 by 304, we get 3 with a remainder of 208.
Write down 3 as next digit of the result. 
Result so far: 92242.2039473
If we subtract 912 from 1120, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 16:
When dividing 2080 by 304, we get 6 with a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 92242.20394736
If we take 1824 away from 2080, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 92242.20394736 and a remainder of 2.56e-07.
