487309 ÷ 43 
The aim is to understand the frequency of 43 in 487309.

Step 1:
43 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 43

Advancing to step 2:
If we divide 48 by 43, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 43 from 48, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 43

Advancing to step 3:
43 can be fit into 57 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 11.0
If we take 43 away from 57, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 43

Going ahead to step 4:
143 divided by 43 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 129 away from 143, we end up with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 43

Let's proceed to step 5:
If we divide 140 by 43, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1133.0
Deduct 129 from 140 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 43

Moving on to step 6:
43 goes into 119 2 times with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 11332.0
The remainder is 33 after subtracting 86 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
When dividing 330 by 43, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 11332.7
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
43 goes into 290 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 11332.76
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 43 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 11332.767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 11332.7674
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
43 goes into 180 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11332.76744
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 11332.76744, with a leftover of 8e-06.
