19031480 ÷ 43 
The aim is to understand the frequency of 43 in 19031480.

Step 1:
1 divided by 43 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 43

Step 2:
If we divide 19 by 43, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 43

Let's proceed to step 3:
If we divide 190 by 43, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 172 from 190, we get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 43

Step 4:
183 divided by 43 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 172 from 183 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 43

Going ahead to step 5:
The number 43 fits into 111 2 times, leaving a remainder of 25.
The next digit of our result is 2. 
Result so far: 442.0
If we subtract 86 from 111, we get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 43

Moving on to step 6:
254 divided by 43 is 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 4425.0
If we take 215 away from 254, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 43

Moving on to step 7:
43 can be fit into 398 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 44259.0
Subtracting 387 from 398 leaves us with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 43

Going ahead to step 8:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 442592.0
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 442592.5
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 43, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 442592.55
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 442592.55 with a remainder of 0.035.
