We're dividing 49396 by 43 
The aim is to understand the frequency of 43 in 49396.

Step 1:
The number 43 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 43

Moving on to step 2:
If we divide 49 by 43, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 49, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 43

Going ahead to step 3:
43 can be fit into 63 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 43 from 63 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

Going ahead to step 4:
43 goes into 209 4 times with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we take 172 away from 209, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 43

Let's proceed to step 5:
The number 43 fits into 376 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1148.0
Deduct 344 from 376 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.

Going ahead to step 6:
320 divided by 43 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1148.7
Subtract 301 from 320 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 43, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 1148.74
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
180 divided by 43 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1148.744
If we take 172 away from 180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1148.744 and a remainder of 0.0008.
