We're dividing 431908 by 49 
The aim is to understand the frequency of 49 in 431908.

Advancing to step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 49

Step 2:
43 divided by 49 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 49

On to step 3:
431 divided by 49 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 39 after subtracting 392 from 431.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 49

Moving on to step 4:
When dividing 399 by 49, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 392 from 399 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 49

Let's proceed to step 5:
70 divided by 49 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 881.0
Subtract 49 from 70 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 49

Step 6:
49 goes into 218 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 8814.0
Deduct 196 from 218 and we're left 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.

Going ahead to step 7:
When dividing 220 by 49, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8814.4
Subtract 196 from 220 to 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.

Moving on to step 8:
49 goes into 240 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 8814.44
The remainder is 44 after subtracting 196 from 240.
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 8814.44 with a remainder of 0.044.
