Let's divide 28740615 by 520
The aim is to understand the frequency of 520 in 28740615.

Moving on to step 1:
2 divided by 520 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 520

Advancing to step 2:
If we divide 28 by 520, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 520

Moving on to step 3:
520 goes into 287 0 times with a remainder of 287.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 287 leaves us with 287.
Grab the next digit (4) from the dividend, add it to 287, then carry on: 2874 / 520

Step 4:
When dividing 2874 by 520, we get 5 with a remainder of 274.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 274 after subtracting 2600 from 2874.
Include the next digit (0) from the dividend after 274, then repeat: 2740 / 520

Going ahead to step 5:
The number 520 fits into 2740 5 times, leaving a remainder of 140.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 2600 from 2740 leaves us with 140.
Fetch the next digit (6) from the dividend, attach it to 140 and continue: 1406 / 520

Going ahead to step 6:
1406 divided by 520 is 2 with a remainder of 366.
The number 2 becomes the next digit in our result. 
Result so far: 552.0
If we subtract 1040 from 1406, we get 366.
Take the next digit (1) from the dividend and append it to 366, then repeat: 3661 / 520

Moving on to step 7:
When dividing 3661 by 520, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 5527.0
If we take 3640 away from 3661, we end up with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 520

Let's proceed to step 8:
215 divided by 520 is 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 55270.0
Subtracting 0 from 215 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 9:
If we divide 2150 by 520, we get 4 and a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 55270.4
Subtracting 2080 from 2150 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 520 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 55270.41
Subtract 520 from 700 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
When dividing 1800 by 520, we get 3 with a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 55270.413
Deduct 1560 from 1800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
If we divide 2400 by 520, we get 4 and a remainder of 320.
The next digit of our result is 4. 
Result so far: 55270.4134
Subtracting 2080 from 2400 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
520 goes into 3200 6 times with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 55270.41346
The remainder is 80 after subtracting 3120 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
520 goes into 800 1 times with a remainder of 280.
The next digit of our result is 1. 
Result so far: 55270.413461
The remainder is 280 after subtracting 520 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
520 goes into 2800 5 times with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 55270.4134615
Deduct 2600 from 2800 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
The number 520 fits into 2000 3 times, leaving a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 55270.41346153
Subtracting 1560 from 2000 leaves us 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.

The quotient of the division is 55270.41346153, and the remainder is 4.4e-07.
