64413 ÷ 53 
The aim is to understand the frequency of 53 in 64413.

Moving on to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 53

Moving on to step 2:
53 goes into 64 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 53 away from 64, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 53

Let's proceed to step 3:
If we divide 114 by 53, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 8 after subtracting 106 from 114.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 53

Step 4:
53 can be fit into 81 1 times, resulting in a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 121.0
The remainder is 28 after subtracting 53 from 81.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 53

On to step 5:
If we divide 283 by 53, we get 5 and a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 1215.0
Subtracting 265 from 283 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 6:
53 goes into 180 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 1215.3
If we take 159 away from 180, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
53 can be fit into 210 3 times, resulting in a remainder of 51.
The next digit of our result is 3. 
Result so far: 1215.33
If we subtract 159 from 210, we 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.

The final result is 1215.33 with a remainder of 0.051.
