13988555 divided by 313 
The aim is to understand the frequency of 313 in 13988555.

Step 1:
When dividing 1 by 313, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 313

Advancing to step 2:
If we divide 13 by 313, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 313

Step 3:
139 divided by 313 is 0 with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 139 and we're left with 139.
Bring next digit (8) of the dividend behind the 139 and repeat the process: 1398 / 313

On to step 4:
The number 313 fits into 1398 4 times, leaving a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 146 after subtracting 1252 from 1398.
Take the next digit (8) from the dividend and append it to 146, then repeat: 1468 / 313

On to step 5:
1468 divided by 313 is 4 with a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 1252 from 1468 and we're left with 216.
Bring next digit (5) of the dividend behind the 216 and repeat the process: 2165 / 313

Advancing to step 6:
313 goes into 2165 6 times with a remainder of 287.
Use 6 as the next digit of our solution. 
Result so far: 446.0
Deduct 1878 from 2165 and we're left with 287.
Take the next digit (5) from the dividend and append it to 287, then repeat: 2875 / 313

Moving on to step 7:
If we divide 2875 by 313, we get 9 and a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 4469.0
Subtracting 2817 from 2875 leaves us with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 313

Moving on to step 8:
313 goes into 585 1 times with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 44691.0
The remainder is 272 after subtracting 313 from 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
313 can be fit into 2720 8 times, resulting in a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 44691.8
Subtracting 2504 from 2720 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 10:
When dividing 2160 by 313, we get 6 with a remainder of 282.
Record the quotient 6 as the next digit in the result. 
Result so far: 44691.86
If we take 1878 away from 2160, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 11:
If we divide 2820 by 313, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 44691.869
Subtracting 2817 from 2820 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
30 divided by 313 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 44691.869
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 313 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 44691.869
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 44691.869 with a balance of 0.0003.
