We look at the division of 432426 by 67 
The aim is to understand the frequency of 67 in 432426.

On to step 1:
If we divide 4 by 67, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 67

Moving on to step 2:
43 divided by 67 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 67

Let's proceed to step 3:
67 can be fit into 432 6 times, resulting in a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 402 away from 432, we end up with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 67

On to step 4:
The number 67 fits into 304 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 268 from 304 leaves us with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 67

Going ahead to step 5:
362 divided by 67 is 5 with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 645.0
If we take 335 away from 362, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 67

On to step 6:
When dividing 276 by 67, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 6454.0
The remainder is 8 after subtracting 268 from 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 67 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 6454.1
The remainder is 13 after subtracting 67 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
When dividing 130 by 67, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 6454.11
The remainder is 63 after subtracting 67 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 6454.11 with a remainder of 0.063.
