We look at the division of 280212 by 49 
The aim is to understand the frequency of 49 in 280212.

Moving on to step 1:
49 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 49

Step 2:
28 divided by 49 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 49

Let's proceed to step 3:
If we divide 280 by 49, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 245 from 280 and we're left with 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 49

Moving on to step 4:
49 goes into 352 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 343 away from 352, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 49

Advancing to step 5:
The number 49 fits into 91 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 571.0
The remainder is 42 after subtracting 49 from 91.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 49

Let's proceed to step 6:
When dividing 422 by 49, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 5718.0
The remainder is 30 after subtracting 392 from 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
49 goes into 300 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 5718.6
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 49 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 5718.61
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 5718.612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 49, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 5718.6122
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.

After the division, we end up with 5718.6122 and a remainder of 0.00022.
