85551935 ÷ 43 
The aim is to understand the frequency of 43 in 85551935.

Step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 43

Let's proceed to step 2:
If we divide 85 by 43, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 43 from 85 leaves us with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 43

Step 3:
If we divide 425 by 43, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 387 away from 425, we end up with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 43

Step 4:
When dividing 385 by 43, we get 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 198.0
Deduct 344 from 385 and we're left with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 43

Advancing to step 5:
The number 43 fits into 411 9 times, leaving a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 1989.0
If we subtract 387 from 411, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 43

Going ahead to step 6:
If we divide 249 by 43, we get 5 and a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 19895.0
If we subtract 215 from 249, we get 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 43

Going ahead to step 7:
43 can be fit into 343 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 198957.0
The remainder is 42 after subtracting 301 from 343.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 43

On to step 8:
425 divided by 43 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1989579.0
Subtracting 387 from 425 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 43, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 1989579.8
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
If we divide 360 by 43, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1989579.88
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1989579.88 with a remainder of 0.016.
