We look at the division of 600549 by 43 
The aim is to understand the frequency of 43 in 600549.

Moving on to step 1:
When dividing 6 by 43, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 43

Let's proceed to step 2:
43 can be fit into 60 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 60 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 43

On to step 3:
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: 13.0
Deduct 129 from 170 and we're left with 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 43

Step 4:
43 can be fit into 415 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 139.0
The remainder is 28 after subtracting 387 from 415.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 43

Advancing to step 5:
284 divided by 43 is 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 1396.0
Subtracting 258 from 284 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 43

Advancing to step 6:
If we divide 269 by 43, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 13966.0
Subtract 258 from 269 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 43 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 13966.2
Deduct 86 from 110 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
43 goes into 240 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 13966.25
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
If we divide 250 by 43, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 13966.255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 13966.255 with a remaining 0.0035.
