We look at the division of 599730 by 43 
The aim is to understand the frequency of 43 in 599730.

Advancing to step 1:
When dividing 5 by 43, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 43

On to step 2:
The number 43 fits into 59 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 43 from 59 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 43

Moving on to step 3:
43 goes into 169 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 129 from 169 and we're left with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 43

Moving on to step 4:
43 can be fit into 407 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 387 from 407 and we're left with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 43

Advancing to step 5:
43 can be fit into 203 4 times, resulting in a remainder of 31.
The next digit of our result is 4. 
Result so far: 1394.0
Subtract 172 from 203 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 43

Let's proceed to step 6:
43 goes into 310 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 13947.0
The remainder is 9 after subtracting 301 from 310.
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.
The number 2 becomes the next digit in our result. 
Result so far: 13947.2
Subtracting 86 from 90 leaves us with 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:
If we divide 40 by 43, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13947.2
Subtract 0 from 40 to 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.

Let's proceed to step 9:
43 goes into 400 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13947.209
If we subtract 387 from 400, we 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.

On to step 10:
The number 43 fits into 130 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13947.2093
Subtracting 129 from 130 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
When dividing 10 by 43, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13947.2093
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.

Going ahead to step 12:
If we divide 100 by 43, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 13947.209302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
43 goes into 140 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 13947.2093023
If we subtract 129 from 140, we 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 14:
110 divided by 43 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 13947.20930232
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.

Our division results in 13947.20930232 with a remaining 2.4e-08.
