43855 divided by 49 
The aim is to understand the frequency of 49 in 43855.

Step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 49

Step 2:
If we divide 43 by 49, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 49

Going ahead to step 3:
When dividing 438 by 49, we get 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 392 from 438 to get 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 49

Let's proceed to step 4:
49 goes into 465 9 times with a remainder of 24.
The next digit of our result is 9. 
Result so far: 89.0
Deduct 441 from 465 and we're left with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 49

Advancing to step 5:
245 divided by 49 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 895.0
If we take 245 away from 245, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 6:
When dividing 0 by 49, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 895.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 49 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 895.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 895.0, with a leftover of 0.0.
