We're dividing 102273 by 43 
The aim is to understand the frequency of 43 in 102273.

Step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 43

On to step 2:
43 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 43

Moving on to step 3:
If we divide 102 by 43, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 86 from 102, we get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 43

Let's proceed to step 4:
43 goes into 162 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 129 from 162 and we're left with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 43

Step 5:
43 goes into 337 7 times with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
The remainder is 36 after subtracting 301 from 337.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 43

Step 6:
43 goes into 363 8 times with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 2378.0
If we take 344 away from 363, we end up 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.

Advancing to step 7:
43 goes into 190 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 2378.4
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
When dividing 180 by 43, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2378.44
If we subtract 172 from 180, we get 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 quotient of the division is 2378.44, and the remainder is 0.008.
