We look at the division of 331769 by 43 
The aim is to understand the frequency of 43 in 331769.

Let's proceed to step 1:
The number 43 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 43

On to step 2:
43 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 43

Advancing to step 3:
When dividing 331 by 43, we get 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 30 after subtracting 301 from 331.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 43

Step 4:
The number 43 fits into 307 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 301 from 307, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 43

Going ahead to step 5:
When dividing 66 by 43, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
Subtracting 43 from 66 leaves us with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 43

Going ahead to step 6:
If we divide 239 by 43, we get 5 and a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 7715.0
Subtract 215 from 239 to get 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 7:
When dividing 240 by 43, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7715.5
Subtracting 215 from 240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7715.55
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 7715.55 with a remaining 0.035.
