We look at the division of 39382864 by 520 
The aim is to understand the frequency of 520 in 39382864.

Let's proceed to step 1:
The number 520 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 520

Going ahead to step 2:
If we divide 39 by 520, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 520

Moving on to step 3:
520 can be fit into 393 0 times, resulting in a remainder of 393.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 393 and we're left with 393.
Take the next digit (8) from the dividend and append it to 393, then repeat: 3938 / 520

Let's proceed to step 4:
The number 520 fits into 3938 7 times, leaving a remainder of 298.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 3640 from 3938 to get 298.
Fetch the next digit (2) from the dividend, attach it to 298 and continue: 2982 / 520

On to step 5:
The number 520 fits into 2982 5 times, leaving a remainder of 382.
Put 5 as the next digit of the answer. 
Result so far: 75.0
The remainder is 382 after subtracting 2600 from 2982.
Take the next digit (8) from the dividend and append it to 382, then repeat: 3828 / 520

Advancing to step 6:
If we divide 3828 by 520, we get 7 and a remainder of 188.
Write down 7 as next digit of the result. 
Result so far: 757.0
If we take 3640 away from 3828, we end up with 188.
Append the next digit (6) from the dividend to 188 and continue with: 1886 / 520

Going ahead to step 7:
1886 divided by 520 is 3 with a remainder of 326.
The next digit of our result is 3. 
Result so far: 7573.0
Subtract 1560 from 1886 to get 326.
Fetch the next digit (4) from the dividend, attach it to 326 and continue: 3264 / 520

Step 8:
520 can be fit into 3264 6 times, resulting in a remainder of 144.
The next digit of our result is 6. 
Result so far: 75736.0
Subtracting 3120 from 3264 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 9:
520 goes into 1440 2 times with a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 75736.2
If we take 1040 away from 1440, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
520 goes into 4000 7 times with a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 75736.27
If we subtract 3640 from 4000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 75736.276
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 75736.2769
The remainder is 120 after subtracting 4680 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 75736.27692
Deduct 1040 from 1200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
520 goes into 1600 3 times with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 75736.276923
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
If we divide 400 by 520, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 75736.276923
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
The number 520 fits into 4000 7 times, leaving a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 75736.27692307
Deduct 3640 from 4000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 75736.27692307, and the remainder is 3.6e-07.
