We're dividing 43391892 by 43 
The aim is to understand the frequency of 43 in 43391892.

Going ahead to step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 43

Advancing to step 2:
43 divided by 43 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 43 from 43.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 43

Moving on to step 3:
3 divided by 43 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

Let's proceed to step 4:
43 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 43

Let's proceed to step 5:
43 goes into 391 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 1009.0
Deduct 387 from 391 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 43

Step 6:
If we divide 48 by 43, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 10091.0
The remainder is 5 after subtracting 43 from 48.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 43

Step 7:
The number 43 fits into 59 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 100911.0
If we take 43 away from 59, we end up with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 43

Step 8:
43 goes into 162 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 1009113.0
Deduct 129 from 162 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
43 goes into 330 7 times with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 1009113.7
Deduct 301 from 330 and we're left 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 10:
290 divided by 43 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1009113.76
Deduct 258 from 290 and we're left with 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 11:
320 divided by 43 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1009113.767
If we take 301 away from 320, we end up with 19.
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 12:
43 can be fit into 190 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1009113.7674
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
43 goes into 180 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1009113.76744
Deduct 172 from 180 and we're left 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.

Our division results in 1009113.76744 with a remaining 8e-06.
