805007 divided by 53 
The aim is to understand the frequency of 53 in 805007.

Moving on to step 1:
8 divided by 53 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 53

Going ahead to step 2:
80 divided by 53 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 53 from 80 to get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 53

Moving on to step 3:
275 divided by 53 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 265 from 275 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 53

Let's proceed to step 4:
When dividing 100 by 53, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we subtract 53 from 100, we get 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 53

Step 5:
The number 53 fits into 470 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 1518.0
Subtract 424 from 470 to get 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 53

Step 6:
The number 53 fits into 467 8 times, leaving a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 15188.0
Subtracting 424 from 467 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 53 fits into 430 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 15188.8
If we subtract 424 from 430, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 53, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 15188.81
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
53 goes into 70 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 15188.811
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 15188.811 and a remainder of 0.0017.
