We look at the division of 131484 by 43 
The aim is to understand the frequency of 43 in 131484.

Going ahead to step 1:
If we divide 1 by 43, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 43

Going ahead to step 2:
If we divide 13 by 43, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 43

Advancing to step 3:
43 goes into 131 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we take 129 away from 131, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 43

Let's proceed to step 4:
When dividing 24 by 43, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 24, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 43

Going ahead to step 5:
248 divided by 43 is 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 305.0
The remainder is 33 after subtracting 215 from 248.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 43

Moving on to step 6:
43 goes into 334 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 3057.0
The remainder is 33 after subtracting 301 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
43 goes into 330 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 3057.7
Subtracting 301 from 330 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
If we divide 290 by 43, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 3057.76
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
43 goes into 320 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 3057.767
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.

Let's proceed to step 10:
43 goes into 190 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 3057.7674
Deduct 172 from 190 and we're left 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 11:
43 can be fit into 180 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3057.76744
Subtracting 172 from 180 leaves us 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.

The quotient of the division is 3057.76744, and the remainder is 8e-06.
