We look at the division of 20691201 by 313 
The aim is to understand the frequency of 313 in 20691201.

Step 1:
The number 313 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 313

Going ahead to step 2:
313 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 313

On to step 3:
When dividing 206 by 313, we get 0 with a remainder of 206.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 206 to get 206.
Fetch the next digit (9) from the dividend, attach it to 206 and continue: 2069 / 313

Going ahead to step 4:
313 can be fit into 2069 6 times, resulting in a remainder of 191.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 1878 from 2069, we get 191.
Include the next digit (1) from the dividend after 191, then repeat: 1911 / 313

Moving on to step 5:
313 goes into 1911 6 times with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 33 after subtracting 1878 from 1911.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 313

Moving on to step 6:
332 divided by 313 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 661.0
If we subtract 313 from 332, we get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 313

Step 7:
190 divided by 313 is 0 with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 6610.0
Subtracting 0 from 190 leaves us with 190.
Fetch the next digit (1) from the dividend, attach it to 190 and continue: 1901 / 313

Moving on to step 8:
The number 313 fits into 1901 6 times, leaving a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 66106.0
Subtract 1878 from 1901 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
230 divided by 313 is 0 with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 66106.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
If we divide 2300 by 313, we get 7 and a remainder of 109.
The number 7 becomes the next digit in our result. 
Result so far: 66106.07
Subtracting 2191 from 2300 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
313 goes into 1090 3 times with a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 66106.073
If we take 939 away from 1090, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 12:
If we divide 1510 by 313, we get 4 and a remainder of 258.
The number 4 becomes the next digit in our result. 
Result so far: 66106.0734
If we subtract 1252 from 1510, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 13:
The number 313 fits into 2580 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 66106.07348
If we take 2504 away from 2580, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
313 can be fit into 760 2 times, resulting in a remainder of 134.
The next digit of our result is 2. 
Result so far: 66106.073482
If we subtract 626 from 760, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 15:
313 goes into 1340 4 times with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 66106.0734824
Deduct 1252 from 1340 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 16:
313 can be fit into 880 2 times, resulting in a remainder of 254.
Put 2 as the next digit of the answer. 
Result so far: 66106.07348242
If we subtract 626 from 880, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 66106.07348242, with a leftover of 2.54e-07.
