We divide 852431 by 43
The aim is to understand the frequency of 43 in 852431.

Step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 43

Step 2:
If we divide 85 by 43, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 43 away from 85, we end up with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 43

Moving on to step 3:
43 can be fit into 422 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 387 from 422, we get 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 43

Let's proceed to step 4:
When dividing 354 by 43, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 198.0
Subtract 344 from 354 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 43

Going ahead to step 5:
When dividing 103 by 43, we get 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1982.0
The remainder is 17 after subtracting 86 from 103.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 43

Moving on to step 6:
When dividing 171 by 43, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 19823.0
If we take 129 away from 171, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
420 divided by 43 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 19823.9
Subtract 387 from 420 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
If we divide 330 by 43, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 19823.97
The remainder is 29 after subtracting 301 from 330.
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 9:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 19823.976
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.

Let's proceed to step 10:
When dividing 320 by 43, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 19823.9767
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 11:
190 divided by 43 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 19823.97674
Subtract 172 from 190 to 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.

Moving on to step 12:
43 goes into 180 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19823.976744
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 result is 19823.976744 with a remainder of 8e-07.
