We look at the division of 880075 by 53 
The aim is to understand the frequency of 53 in 880075.

Going ahead to step 1:
8 divided by 53 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 53

Step 2:
53 goes into 88 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 35 after subtracting 53 from 88.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 53

Moving on to step 3:
The number 53 fits into 350 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 32 after subtracting 318 from 350.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 53

Let's proceed to step 4:
320 divided by 53 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we subtract 318 from 320, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 53

Let's proceed to step 5:
53 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 1660.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 53

Let's proceed to step 6:
When dividing 275 by 53, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 16605.0
Deduct 265 from 275 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 53, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 16605.1
Subtract 53 from 100 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
If we divide 470 by 53, we get 8 and a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 16605.18
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 16605.188
Subtract 424 from 460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 16605.188 and a remainder of 0.0036.
