Let's divide 86452 by 43
The aim is to understand the frequency of 43 in 86452.

Going ahead to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 43

Step 2:
86 divided by 43 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 86 away from 86, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 43

Going ahead to step 3:
The number 43 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 43

Moving on to step 4:
The number 43 fits into 45 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 201.0
Subtracting 43 from 45 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 43

Going ahead to step 5:
The number 43 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 2010.0
Deduct 0 from 22 and we're left 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.

Going ahead to step 6:
220 divided by 43 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2010.5
Deduct 215 from 220 and we're left 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.

Let's proceed to step 7:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 2010.51
If we subtract 43 from 50, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 43, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 2010.511
Deduct 43 from 70 and we're left 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.

Our division results in 2010.511 with a remaining 0.0027.
