Let's divide 855808 by 43
The aim is to understand the frequency of 43 in 855808.

Moving on to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 43

Step 2:
The number 43 fits into 85 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 43 from 85 to get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 43

Step 3:
When dividing 425 by 43, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 387 from 425, we get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 43

Going ahead to step 4:
43 goes into 388 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
If we subtract 387 from 388, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 43

Going ahead to step 5:
If we divide 10 by 43, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1990.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 43

Advancing to step 6:
43 can be fit into 108 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 19902.0
If we take 86 away from 108, we end up 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.

Advancing to step 7:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 19902.5
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.

Moving on to step 8:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 19902.51
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 43 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 19902.511
If we take 43 away from 70, we end up 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.

The final outcome is 19902.511, with a leftover of 0.0027.
