583982 divided by 43 
The aim is to understand the frequency of 43 in 583982.

Let's proceed to step 1:
5 divided by 43 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 43

Going ahead to step 2:
If we divide 58 by 43, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 43 from 58 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 43

Step 3:
The number 43 fits into 153 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 129 from 153, we get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 43

Advancing to step 4:
When dividing 249 by 43, we get 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 135.0
If we subtract 215 from 249, we get 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 43

Let's proceed to step 5:
The number 43 fits into 348 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1358.0
Subtracting 344 from 348 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 43

Moving on to step 6:
If we divide 42 by 43, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 13580.0
Subtract 0 from 42 to 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.

On to step 7:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 13580.9
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.

Moving on to step 8:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 13580.97
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.

Let's proceed to step 9:
290 divided by 43 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 13580.976
Deduct 258 from 290 and we're left 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 10:
If we divide 320 by 43, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 13580.9767
Deduct 301 from 320 and we're left 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.

Step 11:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 13580.97674
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.

Going ahead to step 12:
When dividing 180 by 43, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 13580.976744
If we take 172 away from 180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 13580.976744 with a remaining 8e-07.
