We're dividing 392749 by 43 
The aim is to understand the frequency of 43 in 392749.

On to step 1:
When dividing 3 by 43, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 43

On to step 2:
If we divide 39 by 43, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 43

Let's proceed to step 3:
392 divided by 43 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 387 from 392 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 43

Moving on to step 4:
If we divide 57 by 43, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 43 from 57 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 43

On to step 5:
43 goes into 144 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 913.0
The remainder is 15 after subtracting 129 from 144.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 43

Advancing to step 6:
159 divided by 43 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 9133.0
Deduct 129 from 159 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
When dividing 300 by 43, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 9133.6
Deduct 258 from 300 and we're left 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.

Moving on to step 8:
If we divide 420 by 43, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 9133.69
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 9133.697
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
When dividing 290 by 43, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 9133.6976
Subtracting 258 from 290 leaves us 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.

Advancing to step 11:
320 divided by 43 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 9133.69767
Subtracting 301 from 320 leaves us 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:
If we divide 190 by 43, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 9133.697674
If we take 172 away from 190, we end up with 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 13:
43 can be fit into 180 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 9133.6976744
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.

In conclusion, the division gives 9133.6976744 with a balance of 8e-08.
