We look at the division of 725511 by 67 
The aim is to understand the frequency of 67 in 725511.

Moving on to step 1:
67 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 67

On to step 2:
When dividing 72 by 67, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 67 away from 72, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 67

Moving on to step 3:
When dividing 55 by 67, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 67

Going ahead to step 4:
67 goes into 555 8 times with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtracting 536 from 555 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 67

Step 5:
If we divide 191 by 67, we get 2 and a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 1082.0
The remainder is 57 after subtracting 134 from 191.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 67

Advancing to step 6:
67 goes into 571 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 10828.0
Deduct 536 from 571 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
67 can be fit into 350 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10828.5
If we subtract 335 from 350, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 67, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 10828.52
Deduct 134 from 150 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 67, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 10828.522
If we subtract 134 from 160, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 10828.522, with a leftover of 0.0026.
