We look at the division of 55069389 by 115 
The aim is to understand the frequency of 115 in 55069389.

Going ahead to step 1:
5 divided by 115 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 115

Going ahead to step 2:
115 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 115

Going ahead to step 3:
When dividing 550 by 115, we get 4 with a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 460 from 550, we get 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 115

Advancing to step 4:
115 can be fit into 906 7 times, resulting in a remainder of 101.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 101 after subtracting 805 from 906.
Bring next digit (9) of the dividend behind the 101 and repeat the process: 1019 / 115

Moving on to step 5:
If we divide 1019 by 115, we get 8 and a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we take 920 away from 1019, we end up with 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 115

Advancing to step 6:
993 divided by 115 is 8 with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 4788.0
If we take 920 away from 993, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 115

Moving on to step 7:
If we divide 738 by 115, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 47886.0
If we subtract 690 from 738, we get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 115

Moving on to step 8:
115 goes into 489 4 times with a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 478864.0
If we subtract 460 from 489, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
When dividing 290 by 115, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 478864.2
The remainder is 60 after subtracting 230 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 115 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 478864.25
If we take 575 away from 600, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
115 can be fit into 250 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 478864.252
If we subtract 230 from 250, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 115 fits into 200 1 times, leaving a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 478864.2521
If we subtract 115 from 200, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
If we divide 850 by 115, we get 7 and a remainder of 45.
The next digit of our result is 7. 
Result so far: 478864.25217
If we take 805 away from 850, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
115 goes into 450 3 times with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 478864.252173
Subtracting 345 from 450 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
When dividing 1050 by 115, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 478864.2521739
Subtracting 1035 from 1050 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
The number 115 fits into 150 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 478864.25217391
The remainder is 35 after subtracting 115 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 478864.25217391 with a remaining 3.5e-08.
