Let's divide 75314915 by 307
The aim is to understand the frequency of 307 in 75314915.

Going ahead to step 1:
7 divided by 307 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 307

Let's proceed to step 2:
The number 307 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 307

Advancing to step 3:
307 goes into 753 2 times with a remainder of 139.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 614 from 753 leaves us with 139.
Bring next digit (1) of the dividend behind the 139 and repeat the process: 1391 / 307

Going ahead to step 4:
If we divide 1391 by 307, we get 4 and a remainder of 163.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 1228 from 1391 to get 163.
Include the next digit (4) from the dividend after 163, then repeat: 1634 / 307

Going ahead to step 5:
307 goes into 1634 5 times with a remainder of 99.
Write down 5 as next digit of the result. 
Result so far: 245.0
If we take 1535 away from 1634, we end up with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 307

Advancing to step 6:
307 can be fit into 999 3 times, resulting in a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 2453.0
If we subtract 921 from 999, we get 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 307

Going ahead to step 7:
When dividing 781 by 307, we get 2 with a remainder of 167.
The number 2 becomes the next digit in our result. 
Result so far: 24532.0
If we take 614 away from 781, we end up with 167.
Take the next digit (5) from the dividend and append it to 167, then repeat: 1675 / 307

Advancing to step 8:
307 goes into 1675 5 times with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 245325.0
Subtract 1535 from 1675 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 9:
If we divide 1400 by 307, we get 4 and a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 245325.4
If we take 1228 away from 1400, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
307 goes into 1720 5 times with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 245325.45
If we subtract 1535 from 1720, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
If we divide 1850 by 307, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 245325.456
Deduct 1842 from 1850 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.

Moving on to step 12:
307 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 245325.456
If we take 0 away from 80, we end up with 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 13:
307 goes into 800 2 times with a remainder of 186.
The number 2 becomes the next digit in our result. 
Result so far: 245325.45602
If we take 614 away from 800, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
307 goes into 1860 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 245325.456026
The remainder is 18 after subtracting 1842 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
If we divide 180 by 307, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 245325.456026
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
307 can be fit into 1800 5 times, resulting in a remainder of 265.
The next digit of our result is 5. 
Result so far: 245325.45602605
The remainder is 265 after subtracting 1535 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The quotient of the division is 245325.45602605, and the remainder is 2.65e-07.
