383854 divided by 43 
The aim is to understand the frequency of 43 in 383854.

Let's proceed to step 1:
43 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 43

Going ahead to step 2:
43 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 43

Let's proceed to step 3:
When dividing 383 by 43, we get 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 344 from 383, we get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 43

Let's proceed to step 4:
The number 43 fits into 398 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtract 387 from 398 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 43

Step 5:
115 divided by 43 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 892.0
Subtracting 86 from 115 leaves us with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 43

Step 6:
294 divided by 43 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 8926.0
If we take 258 away from 294, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
When dividing 360 by 43, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8926.8
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
160 divided by 43 is 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 8926.83
Subtracting 129 from 160 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
The number 43 fits into 310 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 8926.837
Subtracting 301 from 310 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
90 divided by 43 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 8926.8372
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 43 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8926.8372
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
43 can be fit into 400 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 8926.837209
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
43 goes into 130 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 8926.8372093
Subtracting 129 from 130 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
The number 43 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8926.8372093
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 8926.8372093, with a leftover of 1e-08.
