We're dividing 36702376 by 520 
The aim is to understand the frequency of 520 in 36702376.

On to step 1:
520 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 520

Going ahead to step 2:
If we divide 36 by 520, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 520

Let's proceed to step 3:
520 can be fit into 367 0 times, resulting in a remainder of 367.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 367 to get 367.
Fetch the next digit (0) from the dividend, attach it to 367 and continue: 3670 / 520

Let's proceed to step 4:
520 can be fit into 3670 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 3640 from 3670, we get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 520

On to step 5:
When dividing 302 by 520, we get 0 with a remainder of 302.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 302, we get 302.
Grab the next digit (3) from the dividend, add it to 302, then carry on: 3023 / 520

Step 6:
3023 divided by 520 is 5 with a remainder of 423.
Put 5 as the next digit of the answer. 
Result so far: 705.0
If we take 2600 away from 3023, we end up with 423.
Bring next digit (7) of the dividend behind the 423 and repeat the process: 4237 / 520

Going ahead to step 7:
520 goes into 4237 8 times with a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 7058.0
Subtract 4160 from 4237 to get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 520

Advancing to step 8:
520 can be fit into 776 1 times, resulting in a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 70581.0
The remainder is 256 after subtracting 520 from 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 9:
When dividing 2560 by 520, we get 4 with a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 70581.4
The remainder is 480 after subtracting 2080 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 10:
When dividing 4800 by 520, we get 9 with a remainder of 120.
The next digit of our result is 9. 
Result so far: 70581.49
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.

Let's proceed to step 11:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
The next digit of our result is 2. 
Result so far: 70581.492
If we take 1040 away from 1200, we end up 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.

Step 12:
520 goes into 1600 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 70581.4923
Deduct 1560 from 1600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 520 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 70581.4923
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
When dividing 4000 by 520, we get 7 with a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 70581.492307
Subtracting 3640 from 4000 leaves us 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.

On to step 15:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 70581.4923076
The remainder is 480 after subtracting 3120 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 16:
520 goes into 4800 9 times with a remainder of 120.
The next digit of our result is 9. 
Result so far: 70581.49230769
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.

After the division, we end up with 70581.49230769 and a remainder of 1.2e-07.
