404509 ÷ 67 
The aim is to understand the frequency of 67 in 404509.

Moving on to step 1:
4 divided by 67 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 67

Step 2:
When dividing 40 by 67, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 67

Moving on to step 3:
404 divided by 67 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 402 away from 404, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 67

Let's proceed to step 4:
67 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 60.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 67

Going ahead to step 5:
If we divide 250 by 67, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
Subtracting 201 from 250 leaves us with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 67

Moving on to step 6:
499 divided by 67 is 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 6037.0
If we take 469 away from 499, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
67 goes into 300 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 6037.4
If we subtract 268 from 300, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
If we divide 320 by 67, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 6037.44
If we subtract 268 from 320, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 6037.44 and a remainder of 0.052.
