We look at the division of 39884631 by 115 
The aim is to understand the frequency of 115 in 39884631.

On to step 1:
If we divide 3 by 115, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 115

On to step 2:
115 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 115

Step 3:
If we divide 398 by 115, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 53 after subtracting 345 from 398.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 115

On to step 4:
If we divide 538 by 115, we get 4 and a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 460 from 538, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 115

On to step 5:
The number 115 fits into 784 6 times, leaving a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 346.0
Subtracting 690 from 784 leaves us with 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 115

Going ahead to step 6:
When dividing 946 by 115, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 3468.0
If we subtract 920 from 946, we get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 115

Moving on to step 7:
If we divide 263 by 115, we get 2 and a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 34682.0
If we subtract 230 from 263, we get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 115

Advancing to step 8:
When dividing 331 by 115, we get 2 with a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 346822.0
If we subtract 230 from 331, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
1010 divided by 115 is 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 346822.8
If we subtract 920 from 1010, we get 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 10:
900 divided by 115 is 7 with a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 346822.87
The remainder is 95 after subtracting 805 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
115 can be fit into 950 8 times, resulting in a remainder of 30.
The next digit of our result is 8. 
Result so far: 346822.878
The remainder is 30 after subtracting 920 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 115 is 2 with a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 346822.8782
Subtracting 230 from 300 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
115 goes into 700 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 346822.87826
Subtract 690 from 700 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
If we divide 100 by 115, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 346822.87826
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
When dividing 1000 by 115, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 346822.8782608
If we subtract 920 from 1000, 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.

Step 16:
If we divide 800 by 115, we get 6 and a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 346822.87826086
If we subtract 690 from 800, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 346822.87826086, with a leftover of 1.1e-07.
