We look at the division of 649304 by 43 
The aim is to understand the frequency of 43 in 649304.

Moving on to step 1:
6 divided by 43 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 43

Let's proceed to step 2:
If we divide 64 by 43, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 43 from 64 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 43

On to step 3:
43 goes into 219 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 215 from 219, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 43

Advancing to step 4:
43 can be fit into 43 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtracting 43 from 43 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 43

On to step 5:
The number 43 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1510.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 43

Going ahead to step 6:
4 divided by 43 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 15100.0
Deduct 0 from 4 and we're left 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 7:
If we divide 40 by 43, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15100.0
If we take 0 away from 40, we end up with 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 8:
43 goes into 400 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 15100.09
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.

Moving on to step 9:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 15100.093
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.

Let's proceed to step 10:
10 divided by 43 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15100.093
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.

Advancing to step 11:
43 can be fit into 100 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 15100.09302
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 43, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 15100.093023
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.

On to step 13:
43 can be fit into 110 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 15100.0930232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 43 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15100.09302325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 15100.09302325 and a remainder of 2.5e-08.
