We're dividing 588550 by 43 
The aim is to understand the frequency of 43 in 588550.

Step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 43

Moving on to step 2:
43 can be fit into 58 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 43 from 58 leaves us with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 43

Moving on to step 3:
43 goes into 158 3 times with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 29 after subtracting 129 from 158.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 43

Moving on to step 4:
295 divided by 43 is 6 with a remainder of 37.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 258 from 295 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 43

Advancing to step 5:
43 goes into 375 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Deduct 344 from 375 and we're left with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 43

Moving on to step 6:
The number 43 fits into 310 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 13687.0
If we take 301 away from 310, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 43 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 13687.2
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
43 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 13687.2
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
If we divide 400 by 43, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 13687.209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
43 goes into 130 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13687.2093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
43 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13687.2093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 13687.209302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13687.2093023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
110 divided by 43 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 13687.20930232
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 13687.20930232, with a leftover of 2.4e-08.
