We're dividing 187254 by 43 
The aim is to understand the frequency of 43 in 187254.

Let's proceed to step 1:
If we divide 1 by 43, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 43

On to step 2:
43 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 43

Going ahead to step 3:
If we divide 187 by 43, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 172 from 187 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 43

Advancing to step 4:
152 divided by 43 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we subtract 129 from 152, we get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 43

Step 5:
When dividing 235 by 43, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
If we subtract 215 from 235, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 43

Let's proceed to step 6:
43 goes into 204 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4354.0
The remainder is 32 after subtracting 172 from 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 43, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 4354.7
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
43 goes into 190 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4354.74
If we subtract 172 from 190, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 43, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4354.744
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 4354.744 with a remaining 0.0008.
