We're dividing 938638 by 43 
The aim is to understand the frequency of 43 in 938638.

On to step 1:
When dividing 9 by 43, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 43

On to step 2:
43 goes into 93 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 86 from 93 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 43

On to step 3:
The number 43 fits into 78 1 times, leaving a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 43 from 78 leaves us with 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 43

Let's proceed to step 4:
356 divided by 43 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 218.0
If we subtract 344 from 356, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 43

Step 5:
The number 43 fits into 123 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2182.0
The remainder is 37 after subtracting 86 from 123.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 43

Moving on to step 6:
If we divide 378 by 43, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 21828.0
If we take 344 away from 378, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 43, we get 7 and a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 21828.7
Deduct 301 from 340 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
390 divided by 43 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 21828.79
Deduct 387 from 390 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 43, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 21828.79
Subtracting 0 from 30 leaves us 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.

Going ahead to step 10:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 21828.7906
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 11:
When dividing 420 by 43, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 21828.79069
Subtracting 387 from 420 leaves us 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.

On to step 12:
When dividing 330 by 43, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 21828.790697
If we take 301 away from 330, we end up 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.

Moving on to step 13:
43 goes into 290 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 21828.7906976
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.

Moving on to step 14:
43 goes into 320 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 21828.79069767
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.

In conclusion, the division gives 21828.79069767 with a balance of 1.9e-08.
