We look at the division of 30480 by 49 
The aim is to understand the frequency of 49 in 30480.

Going ahead to step 1:
The number 49 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 49

Step 2:
When dividing 30 by 49, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 49

Step 3:
When dividing 304 by 49, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 294 away from 304, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 49

Advancing to step 4:
When dividing 108 by 49, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we subtract 98 from 108, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 49

Advancing to step 5:
100 divided by 49 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 622.0
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
The number 49 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 622.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
49 can be fit into 200 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 622.04
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
49 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 622.04
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 49 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 622.0408
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 49 fits into 80 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 622.04081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
If we divide 310 by 49, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 622.040816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
49 goes into 160 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 622.0408163
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
130 divided by 49 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 622.04081632
Deduct 98 from 130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 622.04081632 with a remainder of 3.2e-08.
