We look at the division of 65515 by 49 
The aim is to understand the frequency of 49 in 65515.

Step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 49

On to step 2:
When dividing 65 by 49, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 49 away from 65, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 49

Let's proceed to step 3:
The number 49 fits into 165 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 147 from 165 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 49

Going ahead to step 4:
The number 49 fits into 181 3 times, leaving a remainder of 34.
The next digit of our result is 3. 
Result so far: 133.0
The remainder is 34 after subtracting 147 from 181.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 49

Going ahead to step 5:
The number 49 fits into 345 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1337.0
Subtracting 343 from 345 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
If we divide 20 by 49, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1337.0
Subtract 0 from 20 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 7:
200 divided by 49 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1337.04
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 49 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1337.04
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 49 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1337.0408
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 49, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1337.04081
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
If we divide 310 by 49, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1337.040816
Subtract 294 from 310 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 49 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 1337.0408163
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
If we divide 130 by 49, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1337.04081632
If we take 98 away from 130, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 1337.04081632 with a balance of 3.2e-08.
