57827027 divided by 520 
The aim is to understand the frequency of 520 in 57827027.

Step 1:
5 divided by 520 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 520

Going ahead to step 2:
520 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 520

Step 3:
520 goes into 578 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 520 away from 578, we end up with 58.
Take the next digit (2) from the dividend and append it to 58, then repeat: 582 / 520

On to step 4:
582 divided by 520 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 520 from 582 and we're left with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 520

Advancing to step 5:
520 can be fit into 627 1 times, resulting in a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Subtracting 520 from 627 leaves us with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 520

Moving on to step 6:
520 can be fit into 1070 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 1112.0
If we take 1040 away from 1070, we end up with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 520

Let's proceed to step 7:
The number 520 fits into 302 0 times, leaving a remainder of 302.
The next digit of our result is 0. 
Result so far: 11120.0
If we subtract 0 from 302, we get 302.
Bring next digit (7) of the dividend behind the 302 and repeat the process: 3027 / 520

Step 8:
520 can be fit into 3027 5 times, resulting in a remainder of 427.
The next digit of our result is 5. 
Result so far: 111205.0
Subtract 2600 from 3027 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 9:
When dividing 4270 by 520, we get 8 with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 111205.8
The remainder is 110 after subtracting 4160 from 4270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 520, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 111205.82
The remainder is 60 after subtracting 1040 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
When dividing 600 by 520, we get 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 111205.821
Deduct 520 from 600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
When dividing 800 by 520, we get 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 111205.8211
Deduct 520 from 800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 111205.8211, with a leftover of 0.0028.
