We're dividing 718021 by 43 
The aim is to understand the frequency of 43 in 718021.

Going ahead to step 1:
7 divided by 43 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 43

Let's proceed to step 2:
43 goes into 71 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 43 from 71 leaves us with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 43

Going ahead to step 3:
When dividing 288 by 43, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 258 from 288 to get 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 43

Advancing to step 4:
43 goes into 300 6 times with a remainder of 42.
The next digit of our result is 6. 
Result so far: 166.0
The remainder is 42 after subtracting 258 from 300.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 43

Going ahead to step 5:
When dividing 422 by 43, we get 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 1669.0
If we take 387 away from 422, we end up with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 43

Let's proceed to step 6:
43 can be fit into 351 8 times, resulting in a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 16698.0
Deduct 344 from 351 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 43 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 16698.1
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
270 divided by 43 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 16698.16
The remainder is 12 after subtracting 258 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 43, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 16698.162
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
The number 43 fits into 340 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 16698.1627
The remainder is 39 after subtracting 301 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
When dividing 390 by 43, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 16698.16279
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
If we divide 30 by 43, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 16698.16279
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 43 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 16698.1627906
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
If we divide 420 by 43, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 16698.16279069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 16698.16279069, and the remainder is 3.3e-08.
