Let's divide 19620149 by 307
The aim is to understand the frequency of 307 in 19620149.

Advancing to step 1:
307 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 307

Advancing to step 2:
The number 307 fits into 19 0 times, leaving a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 307

Advancing to step 3:
The number 307 fits into 196 0 times, leaving a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 196, we end up with 196.
Take the next digit (2) from the dividend and append it to 196, then repeat: 1962 / 307

On to step 4:
1962 divided by 307 is 6 with a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 1842 from 1962 to get 120.
Grab the next digit (0) from the dividend, add it to 120, then carry on: 1200 / 307

Step 5:
The number 307 fits into 1200 3 times, leaving a remainder of 279.
Write down 3 as next digit of the result. 
Result so far: 63.0
The remainder is 279 after subtracting 921 from 1200.
Append the next digit (1) from the dividend to 279 and continue with: 2791 / 307

Step 6:
307 can be fit into 2791 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 639.0
Subtract 2763 from 2791 to get 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 307

On to step 7:
When dividing 284 by 307, we get 0 with a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 6390.0
If we take 0 away from 284, we end up with 284.
Append the next digit (9) from the dividend to 284 and continue with: 2849 / 307

Moving on to step 8:
When dividing 2849 by 307, we get 9 with a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 63909.0
Subtracting 2763 from 2849 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
The number 307 fits into 860 2 times, leaving a remainder of 246.
Record the quotient 2 as the next digit in the result. 
Result so far: 63909.2
The remainder is 246 after subtracting 614 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
The number 307 fits into 2460 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 63909.28
Subtract 2456 from 2460 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 307, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 63909.28
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
307 can be fit into 400 1 times, resulting in a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 63909.2801
The remainder is 93 after subtracting 307 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 13:
930 divided by 307 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 63909.28013
Subtract 921 from 930 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
If we divide 90 by 307, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 63909.28013
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
307 can be fit into 900 2 times, resulting in a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 63909.2801302
If we take 614 away from 900, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 16:
307 goes into 2860 9 times with a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 63909.28013029
Subtract 2763 from 2860 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final result is 63909.28013029 with a remainder of 9.7e-08.
