664002 divided by 53 
The aim is to understand the frequency of 53 in 664002.

Advancing to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 53

Moving on to step 2:
If we divide 66 by 53, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 53 from 66, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 53

Advancing to step 3:
53 can be fit into 134 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 106 away from 134, we end up with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 53

Advancing to step 4:
When dividing 280 by 53, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 125.0
If we take 265 away from 280, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 53

Advancing to step 5:
53 can be fit into 150 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1252.0
The remainder is 44 after subtracting 106 from 150.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 53

Let's proceed to step 6:
If we divide 442 by 53, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12528.0
If we subtract 424 from 442, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
53 goes into 180 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 12528.3
Subtracting 159 from 180 leaves us 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.

Let's proceed to step 8:
The number 53 fits into 210 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 12528.33
Subtract 159 from 210 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.

The final outcome is 12528.33, with a leftover of 0.051.
