449883 divided by 43 
The aim is to understand the frequency of 43 in 449883.

Step 1:
43 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 43

On to step 2:
When dividing 44 by 43, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 44, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 43

Let's proceed to step 3:
19 divided by 43 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 19 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 43

Let's proceed to step 4:
If we divide 198 by 43, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 172 from 198 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 43

Let's proceed to step 5:
43 goes into 268 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1046.0
Subtracting 258 from 268 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 43

Advancing to step 6:
The number 43 fits into 103 2 times, leaving a remainder of 17.
The next digit of our result is 2. 
Result so far: 10462.0
If we take 86 away from 103, we end up with 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 7:
When dividing 170 by 43, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 10462.3
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.

Moving on to step 8:
43 can be fit into 410 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 10462.39
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
When dividing 230 by 43, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10462.395
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 10:
If we divide 150 by 43, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 10462.3953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 10462.39534
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
When dividing 380 by 43, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 10462.395348
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
43 goes into 360 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10462.3953488
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 10462.3953488 with a balance of 1.6e-07.
