859779 ÷ 43 
The aim is to understand the frequency of 43 in 859779.

Moving on to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 43

Going ahead to 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
If we take 43 away from 85, we end up with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 43

Let's proceed to step 3:
429 divided by 43 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 387 from 429 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 43

Going ahead to step 4:
43 goes into 427 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 199.0
If we subtract 387 from 427, we get 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 43

Going ahead to step 5:
407 divided by 43 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 1999.0
Subtract 387 from 407 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

Let's proceed to step 6:
If we divide 209 by 43, we get 4 and a remainder of 37.
The next digit of our result is 4. 
Result so far: 19994.0
If we subtract 172 from 209, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 43 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 19994.8
The remainder is 26 after subtracting 344 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
43 goes into 260 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 19994.86
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 43, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19994.86
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 19994.8604
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 43, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 19994.86046
Deduct 258 from 280 and we're left 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.

Moving on to step 12:
43 goes into 220 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 19994.860465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 43, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19994.8604651
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.

Advancing to step 14:
43 goes into 70 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 19994.86046511
Deduct 43 from 70 and we're left 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 result is 19994.86046511 with a remainder of 2.7e-08.
