580877 divided by 53 
The aim is to understand the frequency of 53 in 580877.

Let's proceed to step 1:
5 divided by 53 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 53

Step 2:
53 goes into 58 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 53 from 58 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 53

Let's proceed to step 3:
53 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 50 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 53

Step 4:
If we divide 508 by 53, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 477 from 508 to get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 53

Step 5:
If we divide 317 by 53, we get 5 and a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 1095.0
Subtracting 265 from 317 leaves us with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 53

Moving on to step 6:
53 goes into 527 9 times with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 10959.0
Subtracting 477 from 527 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
500 divided by 53 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 10959.9
The remainder is 23 after subtracting 477 from 500.
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 8:
230 divided by 53 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 10959.94
If we subtract 212 from 230, 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.

Advancing to step 9:
When dividing 180 by 53, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 10959.943
The remainder is 21 after subtracting 159 from 180.
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 10:
The number 53 fits into 210 3 times, leaving a remainder of 51.
The next digit of our result is 3. 
Result so far: 10959.9433
Subtracting 159 from 210 leaves us with 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 quotient of the division is 10959.9433, and the remainder is 0.00051.
