Let's divide 639505 by 43
The aim is to understand the frequency of 43 in 639505.

Going ahead to step 1:
43 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 43

Moving on to step 2:
The number 43 fits into 63 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 20 after subtracting 43 from 63.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 43

Step 3:
When dividing 209 by 43, we get 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 172 away from 209, we end up with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 43

Going ahead to step 4:
375 divided by 43 is 8 with a remainder of 31.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 344 from 375 and we're left with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 43

Moving on to step 5:
43 can be fit into 310 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1487.0
Subtracting 301 from 310 leaves us with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 43

Going ahead to step 6:
95 divided by 43 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 14872.0
Subtracting 86 from 95 leaves us 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:
43 can be fit into 90 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 14872.2
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.

Let's proceed to step 8:
43 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 14872.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 43 fits into 400 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 14872.209
Deduct 387 from 400 and we're left with 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:
If we divide 130 by 43, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 14872.2093
Subtract 129 from 130 to 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.

Moving on to step 11:
If we divide 10 by 43, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 14872.2093
If we subtract 0 from 10, we get 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 goes into 100 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 14872.209302
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.

Going ahead to step 13:
43 goes into 140 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 14872.2093023
The remainder is 11 after subtracting 129 from 140.
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.
Record the quotient 2 as the next digit in the result. 
Result so far: 14872.20930232
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 14872.20930232 and a remainder of 2.4e-08.
