We look at the division of 49514446 by 515 
The aim is to understand the frequency of 515 in 49514446.

Moving on to step 1:
When dividing 4 by 515, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 515

Let's proceed to step 2:
515 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 515

Advancing to step 3:
When dividing 495 by 515, we get 0 with a remainder of 495.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 495, we end up with 495.
Grab the next digit (1) from the dividend, add it to 495, then carry on: 4951 / 515

On to step 4:
4951 divided by 515 is 9 with a remainder of 316.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 4635 from 4951 to get 316.
Grab the next digit (4) from the dividend, add it to 316, then carry on: 3164 / 515

Advancing to step 5:
The number 515 fits into 3164 6 times, leaving a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we subtract 3090 from 3164, we get 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 515

Going ahead to step 6:
If we divide 744 by 515, we get 1 and a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 961.0
Subtract 515 from 744 to get 229.
Grab the next digit (4) from the dividend, add it to 229, then carry on: 2294 / 515

Advancing to step 7:
When dividing 2294 by 515, we get 4 with a remainder of 234.
The next digit of our result is 4. 
Result so far: 9614.0
If we take 2060 away from 2294, we end up with 234.
Bring next digit (6) of the dividend behind the 234 and repeat the process: 2346 / 515

Advancing to step 8:
515 goes into 2346 4 times with a remainder of 286.
Record the quotient 4 as the next digit in the result. 
Result so far: 96144.0
Deduct 2060 from 2346 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 9:
The number 515 fits into 2860 5 times, leaving a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 96144.5
The remainder is 285 after subtracting 2575 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 10:
515 can be fit into 2850 5 times, resulting in a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 96144.55
Subtract 2575 from 2850 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Our division results in 96144.55 with a remaining 0.275.
