81052582 ÷ 43 
The aim is to understand the frequency of 43 in 81052582.

Going ahead to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 43

On to step 2:
If we divide 81 by 43, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 81 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 43

Let's proceed to step 3:
43 can be fit into 380 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 344 from 380 leaves us with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 43

Moving on to step 4:
If we divide 365 by 43, we get 8 and a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 188.0
Subtracting 344 from 365 leaves us with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 43

Going ahead to step 5:
If we divide 212 by 43, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 1884.0
If we take 172 away from 212, we end up with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 43

On to step 6:
43 goes into 405 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 18849.0
Subtracting 387 from 405 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 43

Moving on to step 7:
When dividing 188 by 43, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 188494.0
The remainder is 16 after subtracting 172 from 188.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 43

Going ahead to step 8:
162 divided by 43 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1884943.0
Subtract 129 from 162 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 1884943.7
Deduct 301 from 330 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
When dividing 290 by 43, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 1884943.76
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1884943.767
If we subtract 301 from 320, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
43 can be fit into 190 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1884943.7674
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
43 can be fit into 180 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1884943.76744
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1884943.76744 with a remaining 8e-06.
