52880284 ÷ 520 
The aim is to understand the frequency of 520 in 52880284.

Advancing to step 1:
520 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 520

Going ahead to step 2:
520 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 520

Going ahead to step 3:
If we divide 528 by 520, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 520 from 528, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 520

Let's proceed to step 4:
If we divide 88 by 520, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 88 to get 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 520

Let's proceed to step 5:
880 divided by 520 is 1 with a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 520 from 880 and we're left with 360.
Grab the next digit (2) from the dividend, add it to 360, then carry on: 3602 / 520

Let's proceed to step 6:
520 goes into 3602 6 times with a remainder of 482.
Write down 6 as next digit of the result. 
Result so far: 1016.0
Deduct 3120 from 3602 and we're left with 482.
Grab the next digit (8) from the dividend, add it to 482, then carry on: 4828 / 520

On to step 7:
4828 divided by 520 is 9 with a remainder of 148.
The number 9 becomes the next digit in our result. 
Result so far: 10169.0
If we subtract 4680 from 4828, we get 148.
Bring next digit (4) of the dividend behind the 148 and repeat the process: 1484 / 520

Going ahead to step 8:
The number 520 fits into 1484 2 times, leaving a remainder of 444.
The number 2 becomes the next digit in our result. 
Result so far: 101692.0
Deduct 1040 from 1484 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 9:
520 can be fit into 4440 8 times, resulting in a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 101692.8
Deduct 4160 from 4440 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.

Let's proceed to step 10:
520 goes into 2800 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 101692.85
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
When dividing 2000 by 520, we get 3 with a remainder of 440.
Put 3 as the next digit of the answer. 
Result so far: 101692.853
If we take 1560 away from 2000, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
If we divide 4400 by 520, we get 8 and a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 101692.8538
The remainder is 240 after subtracting 4160 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
The number 520 fits into 2400 4 times, leaving a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 101692.85384
Subtract 2080 from 2400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
If we divide 3200 by 520, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 101692.853846
Subtracting 3120 from 3200 leaves us 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.

Advancing to step 15:
If we divide 800 by 520, we get 1 and a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 101692.8538461
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.

Going ahead to step 16:
520 goes into 2800 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 101692.85384615
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 101692.85384615 with a remainder of 2e-07.
