668067 ÷ 43 
The aim is to understand the frequency of 43 in 668067.

Step 1:
43 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 43

Let's proceed to step 2:
When dividing 66 by 43, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 43 away from 66, we end up with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 43

Advancing to step 3:
238 divided by 43 is 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 215 from 238 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 43

Advancing to step 4:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we subtract 215 from 230, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 43

Moving on to step 5:
If we divide 156 by 43, we get 3 and a remainder of 27.
The next digit of our result is 3. 
Result so far: 1553.0
If we take 129 away from 156, we end up with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 43

Let's proceed to step 6:
If we divide 277 by 43, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 15536.0
If we subtract 258 from 277, 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.

Step 7:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 15536.4
Subtracting 172 from 190 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
43 can be fit into 180 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 15536.44
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 15536.44, and the remainder is 0.008.
