We look at the division of 299773 by 43 
The aim is to understand the frequency of 43 in 299773.

Let's proceed to step 1:
2 divided by 43 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 43

Let's proceed to step 2:
29 divided by 43 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 43

Going ahead to step 3:
If we divide 299 by 43, we get 6 and a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 41 after subtracting 258 from 299.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 43

Moving on to step 4:
43 can be fit into 417 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtracting 387 from 417 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 43

Going ahead to step 5:
If we divide 307 by 43, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 697.0
The remainder is 6 after subtracting 301 from 307.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 43

Moving on to step 6:
When dividing 63 by 43, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 6971.0
If we take 43 away from 63, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
If we divide 200 by 43, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 6971.4
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
When dividing 280 by 43, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 6971.46
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
If we divide 220 by 43, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6971.465
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
43 goes into 50 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 6971.4651
Deduct 43 from 50 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
43 goes into 70 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 6971.46511
If we take 43 away from 70, 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.

The final outcome is 6971.46511, with a leftover of 2.7e-05.
