We look at the division of 9214109 by 307 
The aim is to understand the frequency of 307 in 9214109.

Step 1:
9 divided by 307 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 307

Step 2:
When dividing 92 by 307, we get 0 with a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 92, we get 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 307

Step 3:
If we divide 921 by 307, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 921 from 921.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 307

Going ahead to step 4:
307 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 4 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 307

Going ahead to step 5:
When dividing 41 by 307, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we take 0 away from 41, we end up with 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 307

Moving on to step 6:
410 divided by 307 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 3001.0
Deduct 307 from 410 and we're left with 103.
Grab the next digit (9) from the dividend, add it to 103, then carry on: 1039 / 307

Step 7:
307 can be fit into 1039 3 times, resulting in a remainder of 118.
The next digit of our result is 3. 
Result so far: 30013.0
Subtracting 921 from 1039 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 8:
The number 307 fits into 1180 3 times, leaving a remainder of 259.
Write down 3 as next digit of the result. 
Result so far: 30013.3
If we take 921 away from 1180, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 9:
2590 divided by 307 is 8 with a remainder of 134.
The next digit of our result is 8. 
Result so far: 30013.38
If we take 2456 away from 2590, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
The number 307 fits into 1340 4 times, leaving a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 30013.384
Subtract 1228 from 1340 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
1120 divided by 307 is 3 with a remainder of 199.
Write down 3 as next digit of the result. 
Result so far: 30013.3843
Deduct 921 from 1120 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 12:
307 can be fit into 1990 6 times, resulting in a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 30013.38436
Subtracting 1842 from 1990 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 13:
307 can be fit into 1480 4 times, resulting in a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 30013.384364
Subtract 1228 from 1480 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 14:
2520 divided by 307 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 30013.3843648
If we subtract 2456 from 2520, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
When dividing 640 by 307, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 30013.38436482
Subtract 614 from 640 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 30013.38436482, and the remainder is 2.6e-08.
