726321 ÷ 67 
The aim is to understand the frequency of 67 in 726321.

Advancing to step 1:
The number 67 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 67

Moving on to step 2:
The number 67 fits into 72 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 67 from 72 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 67

Going ahead to step 3:
67 goes into 56 0 times with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 56 and we're left with 56.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 67

Let's proceed to step 4:
67 can be fit into 563 8 times, resulting in a remainder of 27.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 536 from 563 leaves us with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 67

On to step 5:
272 divided by 67 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1084.0
The remainder is 4 after subtracting 268 from 272.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 67

Moving on to step 6:
The number 67 fits into 41 0 times, leaving a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 10840.0
Subtract 0 from 41 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
The number 67 fits into 410 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10840.6
The remainder is 8 after subtracting 402 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 67, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 10840.61
Subtract 67 from 80 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
When dividing 130 by 67, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 10840.611
Subtract 67 from 130 to get 63.
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 outcome is 10840.611, with a leftover of 0.0063.
