453575 ÷ 67 
The aim is to understand the frequency of 67 in 453575.

Step 1:
4 divided by 67 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 67

Going ahead to step 2:
If we divide 45 by 67, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 67

Going ahead to step 3:
453 divided by 67 is 6 with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 402 from 453, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 67

Step 4:
515 divided by 67 is 7 with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we subtract 469 from 515, we get 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 67

Moving on to step 5:
The number 67 fits into 467 6 times, leaving a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
Subtracting 402 from 467 leaves us with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 67

Advancing to step 6:
67 goes into 655 9 times with a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 6769.0
If we take 603 away from 655, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
67 can be fit into 520 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 6769.7
Subtract 469 from 520 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
67 goes into 510 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 6769.77
If we subtract 469 from 510, we 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.

The final outcome is 6769.77, with a leftover of 0.041.
