88950039 ÷ 43 
The aim is to understand the frequency of 43 in 88950039.

On to step 1:
43 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 43

Going ahead to step 2:
If we divide 88 by 43, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 86 from 88, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 43

Advancing to step 3:
43 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 29, we get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 43

Let's proceed to step 4:
If we divide 295 by 43, we get 6 and a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
Subtracting 258 from 295 leaves us with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 43

Going ahead to step 5:
If we divide 370 by 43, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 2068.0
If we subtract 344 from 370, we get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 43

Moving on to step 6:
If we divide 260 by 43, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 20686.0
The remainder is 2 after subtracting 258 from 260.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 43

Going ahead to step 7:
43 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 206860.0
Subtract 0 from 23 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 43

On to step 8:
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: 2068605.0
If we take 215 away from 239, 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 9:
43 can be fit into 240 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2068605.5
If we subtract 215 from 240, we 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.

Going ahead to step 10:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2068605.55
Subtract 215 from 250 to get 35.
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 2068605.55 with a remaining 0.035.
