497574 divided by 43 
The aim is to understand the frequency of 43 in 497574.

Let's proceed to step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 43

Step 2:
43 can be fit into 49 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 43 from 49.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 43

On to step 3:
The number 43 fits into 67 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 43 from 67 to get 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 43

Step 4:
The number 43 fits into 245 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we subtract 215 from 245, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 43

Going ahead to step 5:
43 can be fit into 307 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1157.0
If we subtract 301 from 307, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 43

Advancing to step 6:
When dividing 64 by 43, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 11571.0
Subtract 43 from 64 to 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 7:
43 can be fit into 210 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 11571.4
The remainder is 38 after subtracting 172 from 210.
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 8:
43 goes into 380 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 11571.48
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.

Moving on to step 9:
43 goes into 360 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 11571.488
Deduct 344 from 360 and we're left 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.

The final result is 11571.488 with a remainder of 0.0016.
