419934 ÷ 43 
The aim is to understand the frequency of 43 in 419934.

Advancing to step 1:
4 divided by 43 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 43

Going ahead to step 2:
When dividing 41 by 43, we get 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 43

Step 3:
The number 43 fits into 419 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 32 after subtracting 387 from 419.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 43

Step 4:
The number 43 fits into 329 7 times, leaving a remainder of 28.
The next digit of our result is 7. 
Result so far: 97.0
If we take 301 away from 329, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 43

Going ahead to step 5:
When dividing 283 by 43, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 976.0
If we take 258 away from 283, we end up with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 43

Let's proceed to step 6:
254 divided by 43 is 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 9765.0
Subtracting 215 from 254 leaves us 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.

Advancing to step 7:
390 divided by 43 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9765.9
Subtract 387 from 390 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
If we divide 30 by 43, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 9765.9
If we take 0 away from 30, we end up 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.

Let's proceed to step 9:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 9765.906
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.

Let's proceed to step 10:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 9765.9069
If we take 387 away from 420, we end up 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.

Step 11:
When dividing 330 by 43, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 9765.90697
Subtracting 301 from 330 leaves us 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 12:
When dividing 290 by 43, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 9765.906976
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 43, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 9765.9069767
If we subtract 301 from 320, we 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.

Moving on to step 14:
The number 43 fits into 190 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 9765.90697674
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.

The final outcome is 9765.90697674, with a leftover of 1.8e-08.
