102530 ÷ 49 
The aim is to understand the frequency of 49 in 102530.

Going ahead to step 1:
When dividing 1 by 49, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 49

Step 2:
The number 49 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 49

Let's proceed to step 3:
49 goes into 102 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 98 from 102 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 49

Advancing to step 4:
49 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 49

Going ahead to step 5:
If we divide 453 by 49, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 209.0
If we subtract 441 from 453, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 49

Moving on to step 6:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2092.0
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 49, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2092.4
If we subtract 196 from 220, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
49 goes into 240 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 2092.44
If we take 196 away from 240, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 2092.44 with a remainder of 0.044.
