We look at the division of 304131 by 49 
The aim is to understand the frequency of 49 in 304131.

Going ahead to step 1:
49 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 49

Let's proceed to step 2:
49 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 49

Step 3:
49 goes into 304 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 294 from 304 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 49

Step 4:
When dividing 101 by 49, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Deduct 98 from 101 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 49

Going ahead to step 5:
When dividing 33 by 49, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 620.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 49

Going ahead to step 6:
331 divided by 49 is 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 6206.0
The remainder is 37 after subtracting 294 from 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
If we divide 370 by 49, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 6206.7
Subtracting 343 from 370 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
The number 49 fits into 270 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6206.75
Subtract 245 from 270 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
If we divide 250 by 49, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6206.755
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 6206.755 and a remainder of 0.0005.
