398874 ÷ 43 
The aim is to understand the frequency of 43 in 398874.

Advancing to step 1:
3 divided by 43 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

Advancing to step 2:
If we divide 39 by 43, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 43

Going ahead to step 3:
The number 43 fits into 398 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 11 after subtracting 387 from 398.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 43

Going ahead to step 4:
The number 43 fits into 118 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 86 from 118, we get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 43

Let's proceed to step 5:
43 goes into 327 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 927.0
Subtract 301 from 327 to get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 43

Moving on to step 6:
When dividing 264 by 43, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 9276.0
Deduct 258 from 264 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 43, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 9276.1
If we subtract 43 from 60, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
43 goes into 170 3 times with a remainder of 41.
The next digit of our result is 3. 
Result so far: 9276.13
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
If we divide 410 by 43, we get 9 and a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 9276.139
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
230 divided by 43 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9276.1395
Subtracting 215 from 230 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 9276.13953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
When dividing 210 by 43, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 9276.139534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
43 goes into 380 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 9276.1395348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
360 divided by 43 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 9276.13953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 9276.13953488 with a balance of 1.6e-08.
