We look at the division of 992523 by 49 
The aim is to understand the frequency of 49 in 992523.

Going ahead to step 1:
If we divide 9 by 49, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 49

Going ahead to step 2:
49 goes into 99 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 98 from 99 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 49

On to step 3:
49 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 49

Moving on to step 4:
49 goes into 125 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 202.0
The remainder is 27 after subtracting 98 from 125.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 49

Step 5:
49 can be fit into 272 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 2025.0
The remainder is 27 after subtracting 245 from 272.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 49

On to step 6:
If we divide 273 by 49, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 20255.0
If we subtract 245 from 273, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
If we divide 280 by 49, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 20255.5
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
When dividing 350 by 49, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 20255.57
Subtracting 343 from 350 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 49 fits into 70 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 20255.571
Subtracting 49 from 70 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
The number 49 fits into 210 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 20255.5714
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 49 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 20255.57142
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
When dividing 420 by 49, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 20255.571428
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 49, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 20255.5714285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
49 goes into 350 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 20255.57142857
The remainder is 7 after subtracting 343 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 20255.57142857 and a remainder of 7e-09.
