Let's divide 838398 by 43
The aim is to understand the frequency of 43 in 838398.

Advancing to step 1:
43 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 43

Moving on to step 2:
The number 43 fits into 83 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 43 from 83 and we're left with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 43

Step 3:
The number 43 fits into 408 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 387 from 408, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 43

Going ahead to step 4:
The number 43 fits into 213 4 times, leaving a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
If we subtract 172 from 213, we get 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 43

Going ahead to step 5:
419 divided by 43 is 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 1949.0
Subtract 387 from 419 to get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 43

Step 6:
The number 43 fits into 328 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 19497.0
Subtract 301 from 328 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 43 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 19497.6
If we subtract 258 from 270, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
43 can be fit into 120 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 19497.62
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 43 is 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 19497.627
If we subtract 301 from 340, we get 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 10:
The number 43 fits into 390 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 19497.6279
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.

Let's proceed to step 11:
43 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 19497.6279
Deduct 0 from 30 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.

Advancing to step 12:
300 divided by 43 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 19497.627906
If we subtract 258 from 300, we get 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 13:
43 goes into 420 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 19497.6279069
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 14:
43 goes into 330 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 19497.62790697
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.

Our division results in 19497.62790697 with a remaining 2.9e-08.
