7750525 ÷ 304 
The aim is to understand the frequency of 304 in 7750525.

Step 1:
The number 304 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 304

Going ahead to step 2:
77 divided by 304 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 304

Advancing to step 3:
304 goes into 775 2 times with a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 608 from 775, we get 167.
Bring next digit (0) of the dividend behind the 167 and repeat the process: 1670 / 304

Let's proceed to step 4:
If we divide 1670 by 304, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 25.0
If we take 1520 away from 1670, we end up with 150.
Grab the next digit (5) from the dividend, add it to 150, then carry on: 1505 / 304

Advancing to step 5:
304 can be fit into 1505 4 times, resulting in a remainder of 289.
The next digit of our result is 4. 
Result so far: 254.0
If we subtract 1216 from 1505, we get 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 304

Advancing to step 6:
The number 304 fits into 2892 9 times, leaving a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 2549.0
The remainder is 156 after subtracting 2736 from 2892.
Include the next digit (5) from the dividend after 156, then repeat: 1565 / 304

Moving on to step 7:
304 goes into 1565 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 25495.0
Deduct 1520 from 1565 and we're left 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:
When dividing 450 by 304, we get 1 with a remainder of 146.
Use 1 as the next digit of our solution. 
Result so far: 25495.1
Subtracting 304 from 450 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
304 goes into 1460 4 times with a remainder of 244.
Put 4 as the next digit of the answer. 
Result so far: 25495.14
Subtract 1216 from 1460 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
When dividing 2440 by 304, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 25495.148
Deduct 2432 from 2440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 304, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 25495.148
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
800 divided by 304 is 2 with a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 25495.14802
If we take 608 away from 800, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 13:
304 can be fit into 1920 6 times, resulting in a remainder of 96.
The next digit of our result is 6. 
Result so far: 25495.148026
If we subtract 1824 from 1920, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
When dividing 960 by 304, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 25495.1480263
If we take 912 away from 960, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 15:
The number 304 fits into 480 1 times, leaving a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 25495.14802631
The remainder is 176 after subtracting 304 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 25495.14802631, and the remainder is 1.76e-07.
