We look at the division of 500289 by 43 
The aim is to understand the frequency of 43 in 500289.

Step 1:
43 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 43

Moving on to step 2:
43 goes into 50 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 50, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 43

Let's proceed to step 3:
When dividing 70 by 43, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 43 from 70 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 43

Moving on to step 4:
43 goes into 272 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 258 from 272 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 43

On to step 5:
When dividing 148 by 43, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 1163.0
If we subtract 129 from 148, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 43

Advancing to step 6:
When dividing 199 by 43, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 11634.0
If we take 172 away from 199, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
43 can be fit into 270 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11634.6
The remainder is 12 after subtracting 258 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 43, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 11634.62
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
If we divide 340 by 43, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 11634.627
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
390 divided by 43 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 11634.6279
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
43 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11634.6279
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
43 can be fit into 300 6 times, resulting in a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 11634.627906
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
43 goes into 420 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 11634.6279069
If we subtract 387 from 420, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 11634.62790697
Subtracting 301 from 330 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 11634.62790697, and the remainder is 2.9e-08.
