We look at the division of 25308 by 49 
The aim is to understand the frequency of 49 in 25308.

Let's proceed to step 1:
If we divide 2 by 49, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 49

Going ahead to step 2:
49 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 49

Advancing to step 3:
If we divide 253 by 49, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 245 away from 253, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 49

Advancing to step 4:
When dividing 80 by 49, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 31 after subtracting 49 from 80.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 49

On to step 5:
If we divide 318 by 49, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 516.0
If we take 294 away from 318, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 6:
If we divide 240 by 49, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 516.4
Deduct 196 from 240 and we're left 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.

Step 7:
440 divided by 49 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 516.48
Deduct 392 from 440 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
When dividing 480 by 49, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 516.489
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
390 divided by 49 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 516.4897
Subtracting 343 from 390 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
49 goes into 470 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 516.48979
Subtract 441 from 470 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
49 can be fit into 290 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 516.489795
Subtract 245 from 290 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
450 divided by 49 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 516.4897959
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
49 can be fit into 90 1 times, resulting in a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 516.48979591
Deduct 49 from 90 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 516.48979591, with a leftover of 4.1e-08.
