We look at the division of 73285575 by 115 
The aim is to understand the frequency of 115 in 73285575.

Moving on to step 1:
If we divide 7 by 115, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 115

Advancing to step 2:
115 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 115

Advancing to step 3:
When dividing 732 by 115, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 690 from 732 and we're left with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 115

Let's proceed to step 4:
428 divided by 115 is 3 with a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 345 from 428 to get 83.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 115

Step 5:
The number 115 fits into 835 7 times, leaving a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
Subtract 805 from 835 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 115

Moving on to step 6:
115 goes into 305 2 times with a remainder of 75.
Write down 2 as next digit of the result. 
Result so far: 6372.0
Subtracting 230 from 305 leaves us with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 115

Advancing to step 7:
If we divide 757 by 115, we get 6 and a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 63726.0
Deduct 690 from 757 and we're left with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 115

Let's proceed to step 8:
675 divided by 115 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 637265.0
If we take 575 away from 675, we end up with 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 9:
If we divide 1000 by 115, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 637265.8
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 10:
The number 115 fits into 800 6 times, leaving a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 637265.86
Deduct 690 from 800 and we're left 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 11:
If we divide 1100 by 115, we get 9 and a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 637265.869
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
650 divided by 115 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 637265.8695
If we subtract 575 from 650, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
If we divide 750 by 115, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 637265.86956
Subtracting 690 from 750 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
115 goes into 600 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 637265.869565
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.

Advancing to step 15:
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: 637265.8695652
Subtract 230 from 250 to 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.

On to step 16:
200 divided by 115 is 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 637265.86956521
Deduct 115 from 200 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 637265.86956521 with a remainder of 8.5e-08.
