306078 ÷ 43 
The aim is to understand the frequency of 43 in 306078.

On to step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 43

Going ahead to step 2:
When dividing 30 by 43, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 43

Moving on to step 3:
If we divide 306 by 43, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 301 away from 306, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 43

Advancing to step 4:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 43 away from 50, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 43

Step 5:
If we divide 77 by 43, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 711.0
Subtract 43 from 77 to get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 43

Advancing to step 6:
If we divide 348 by 43, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7118.0
Subtracting 344 from 348 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 43 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7118.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 43 fits into 400 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 7118.09
Subtracting 387 from 400 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
43 can be fit into 130 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 7118.093
Subtracting 129 from 130 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
43 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7118.093
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
43 goes into 100 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 7118.09302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
140 divided by 43 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 7118.093023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 43 fits into 110 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 7118.0930232
Subtract 86 from 110 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7118.09302325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 7118.09302325 and a remainder of 2.5e-08.
