We're dividing 571928 by 53 
The aim is to understand the frequency of 53 in 571928.

On to step 1:
5 divided by 53 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 53

Moving on to step 2:
53 goes into 57 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 53 from 57 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 53

Let's proceed to step 3:
The number 53 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 41 after subtracting 0 from 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 53

On to step 4:
53 goes into 419 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 371 from 419 leaves us with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 53

Moving on to step 5:
If we divide 482 by 53, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 1079.0
The remainder is 5 after subtracting 477 from 482.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 53

Advancing to step 6:
If we divide 58 by 53, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 10791.0
If we take 53 away from 58, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 53 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10791.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
The number 53 fits into 500 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 10791.09
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 10791.094
Subtract 212 from 230 to 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.

Step 10:
53 goes into 180 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 10791.0943
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
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: 10791.09433
The remainder is 51 after subtracting 159 from 210.
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 10791.09433 with a remainder of 5.1e-05.
