We look at the division of 73964863 by 317 
The aim is to understand the frequency of 317 in 73964863.

Going ahead to step 1:
7 divided by 317 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 317

Step 2:
If we divide 73 by 317, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 317

Step 3:
739 divided by 317 is 2 with a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 634 from 739, we get 105.
Include the next digit (6) from the dividend after 105, then repeat: 1056 / 317

Step 4:
317 goes into 1056 3 times with a remainder of 105.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 951 from 1056 to get 105.
Include the next digit (4) from the dividend after 105, then repeat: 1054 / 317

Step 5:
1054 divided by 317 is 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 233.0
Deduct 951 from 1054 and we're left with 103.
Take the next digit (8) from the dividend and append it to 103, then repeat: 1038 / 317

Moving on to step 6:
If we divide 1038 by 317, we get 3 and a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 2333.0
The remainder is 87 after subtracting 951 from 1038.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 317

Step 7:
317 can be fit into 876 2 times, resulting in a remainder of 242.
Use 2 as the next digit of our solution. 
Result so far: 23332.0
Subtract 634 from 876 to get 242.
Take the next digit (3) from the dividend and append it to 242, then repeat: 2423 / 317

Moving on to step 8:
2423 divided by 317 is 7 with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 233327.0
Deduct 2219 from 2423 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
317 can be fit into 2040 6 times, resulting in a remainder of 138.
Write down 6 as next digit of the result. 
Result so far: 233327.6
Subtract 1902 from 2040 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
If we divide 1380 by 317, we get 4 and a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 233327.64
If we take 1268 away from 1380, we end up with 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:
The number 317 fits into 1120 3 times, leaving a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 233327.643
If we subtract 951 from 1120, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 12:
If we divide 1690 by 317, we get 5 and a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 233327.6435
If we subtract 1585 from 1690, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 13:
If we divide 1050 by 317, we get 3 and a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 233327.64353
If we subtract 951 from 1050, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 14:
317 can be fit into 990 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 233327.643533
If we take 951 away from 990, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 233327.643533 with a remainder of 3.9e-06.
