We look at the division of 599995 by 53 
The aim is to understand the frequency of 53 in 599995.

Going ahead to step 1:
If we divide 5 by 53, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 53

Going ahead to step 2:
The number 53 fits into 59 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 53 from 59.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 53

On to step 3:
53 goes into 69 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 53 from 69 and we're left with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 53

Going ahead to step 4:
53 can be fit into 169 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 159 from 169 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 53

Moving on to step 5:
53 goes into 109 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
If we take 106 away from 109, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 53

Moving on to step 6:
53 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 11320.0
If we subtract 0 from 35, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
350 divided by 53 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11320.6
If we subtract 318 from 350, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 53, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 11320.66
The remainder is 2 after subtracting 318 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 11320.66 with a remainder of 0.002.
