97930931 ÷ 307 
The aim is to understand the frequency of 307 in 97930931.

Advancing to step 1:
307 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 307

Let's proceed to step 2:
97 divided by 307 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (9) from the dividend, attach it to 97 and continue: 979 / 307

Step 3:
307 can be fit into 979 3 times, resulting in a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 921 from 979 and we're left with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 307

Moving on to step 4:
583 divided by 307 is 1 with a remainder of 276.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 307 from 583 and we're left with 276.
Include the next digit (0) from the dividend after 276, then repeat: 2760 / 307

Step 5:
When dividing 2760 by 307, we get 8 with a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 318.0
If we take 2456 away from 2760, we end up with 304.
Fetch the next digit (9) from the dividend, attach it to 304 and continue: 3049 / 307

Step 6:
When dividing 3049 by 307, we get 9 with a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 3189.0
Subtracting 2763 from 3049 leaves us with 286.
Include the next digit (3) from the dividend after 286, then repeat: 2863 / 307

Let's proceed to step 7:
When dividing 2863 by 307, we get 9 with a remainder of 100.
Use 9 as the next digit of our solution. 
Result so far: 31899.0
If we take 2763 away from 2863, we end up with 100.
Fetch the next digit (1) from the dividend, attach it to 100 and continue: 1001 / 307

Moving on to step 8:
307 goes into 1001 3 times with a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 318993.0
If we subtract 921 from 1001, 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.

On to step 9:
307 can be fit into 800 2 times, resulting in a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 318993.2
The remainder is 186 after subtracting 614 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
The number 307 fits into 1860 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 318993.26
Subtracting 1842 from 1860 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
180 divided by 307 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 318993.26
If we subtract 0 from 180, we get 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 12:
The number 307 fits into 1800 5 times, leaving a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 318993.2605
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.

Advancing to step 13:
307 goes into 2650 8 times with a remainder of 194.
The number 8 becomes the next digit in our result. 
Result so far: 318993.26058
Subtracting 2456 from 2650 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 14:
If we divide 1940 by 307, we get 6 and a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 318993.260586
The remainder is 98 after subtracting 1842 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 15:
980 divided by 307 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 318993.2605863
The remainder is 59 after subtracting 921 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 16:
590 divided by 307 is 1 with a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 318993.26058631
Deduct 307 from 590 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

After the division, we end up with 318993.26058631 and a remainder of 2.83e-07.
