We look at the division of 870382 by 43 
The aim is to understand the frequency of 43 in 870382.

On to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 43

Let's proceed to step 2:
When dividing 87 by 43, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 1 after subtracting 86 from 87.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 43

Let's proceed to step 3:
10 divided by 43 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 43

Advancing to step 4:
When dividing 103 by 43, we get 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
If we subtract 86 from 103, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 43

Step 5:
If we divide 178 by 43, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2024.0
If we subtract 172 from 178, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 43

Let's proceed to step 6:
62 divided by 43 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 20241.0
If we subtract 43 from 62, we 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 7:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 20241.4
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.

On to step 8:
43 can be fit into 180 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20241.44
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 final outcome is 20241.44, with a leftover of 0.008.
