Let's divide 35189929 by 115
The aim is to understand the frequency of 115 in 35189929.

Going ahead to step 1:
When dividing 3 by 115, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 115

Step 2:
When dividing 35 by 115, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 115

Going ahead to step 3:
When dividing 351 by 115, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 345 from 351 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 115

On to step 4:
The number 115 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 68, we end up with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 115

Moving on to step 5:
115 goes into 689 5 times with a remainder of 114.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
If we subtract 575 from 689, we get 114.
Append the next digit (9) from the dividend to 114 and continue with: 1149 / 115

Step 6:
When dividing 1149 by 115, we get 9 with a remainder of 114.
Write down 9 as next digit of the result. 
Result so far: 3059.0
Subtracting 1035 from 1149 leaves us with 114.
Append the next digit (2) from the dividend to 114 and continue with: 1142 / 115

Moving on to step 7:
When dividing 1142 by 115, we get 9 with a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 30599.0
Subtract 1035 from 1142 to get 107.
Bring next digit (9) of the dividend behind the 107 and repeat the process: 1079 / 115

Going ahead to step 8:
115 goes into 1079 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 305999.0
The remainder is 44 after subtracting 1035 from 1079.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
If we divide 440 by 115, we get 3 and a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 305999.3
Deduct 345 from 440 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
When dividing 950 by 115, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 305999.38
Subtracting 920 from 950 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 11:
When dividing 300 by 115, we get 2 with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 305999.382
If we take 230 away from 300, we end up 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.

Moving on to step 12:
The number 115 fits into 700 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 305999.3826
If we take 690 away from 700, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 115, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 305999.3826
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.

Let's proceed to step 14:
1000 divided by 115 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 305999.382608
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.

Advancing to step 15:
800 divided by 115 is 6 with a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 305999.3826086
If we take 690 away from 800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
115 can be fit into 1100 9 times, resulting in a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 305999.38260869
If we take 1035 away from 1100, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 305999.38260869 with a remainder of 6.5e-08.
