856499 divided by 43 
The aim is to understand the frequency of 43 in 856499.

Going ahead to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 43

Moving on to step 2:
When dividing 85 by 43, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 85, we end up with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 43

Going ahead to step 3:
The number 43 fits into 426 9 times, leaving a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 387 away from 426, we end up with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 43

Step 4:
394 divided by 43 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 199.0
The remainder is 7 after subtracting 387 from 394.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 43

On to step 5:
43 can be fit into 79 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 1991.0
If we take 43 away from 79, we end up with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 43

Going ahead to step 6:
43 goes into 369 8 times with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 19918.0
The remainder is 25 after subtracting 344 from 369.
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 7:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 19918.5
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.

Step 8:
The number 43 fits into 350 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19918.58
Deduct 344 from 350 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 43, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 19918.581
The remainder is 17 after subtracting 43 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
43 can be fit into 170 3 times, resulting in a remainder of 41.
The next digit of our result is 3. 
Result so far: 19918.5813
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
43 goes into 410 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 19918.58139
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
When dividing 230 by 43, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 19918.581395
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
43 goes into 150 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 19918.5813953
Subtract 129 from 150 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
210 divided by 43 is 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 19918.58139534
Subtracting 172 from 210 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.

The quotient of the division is 19918.58139534, and the remainder is 3.8e-08.
