We look at the division of 67297674 by 520 
The aim is to understand the frequency of 520 in 67297674.

Advancing to step 1:
6 divided by 520 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 520

Step 2:
520 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 520

Moving on to step 3:
When dividing 672 by 520, we get 1 with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 520 from 672, we get 152.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 520

Step 4:
If we divide 1529 by 520, we get 2 and a remainder of 489.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1040 from 1529 to get 489.
Bring next digit (7) of the dividend behind the 489 and repeat the process: 4897 / 520

Advancing to step 5:
When dividing 4897 by 520, we get 9 with a remainder of 217.
The next digit of our result is 9. 
Result so far: 129.0
The remainder is 217 after subtracting 4680 from 4897.
Include the next digit (6) from the dividend after 217, then repeat: 2176 / 520

Moving on to step 6:
When dividing 2176 by 520, we get 4 with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 1294.0
Subtract 2080 from 2176 to get 96.
Include the next digit (7) from the dividend after 96, then repeat: 967 / 520

Moving on to step 7:
520 goes into 967 1 times with a remainder of 447.
Record the quotient 1 as the next digit in the result. 
Result so far: 12941.0
Deduct 520 from 967 and we're left with 447.
Fetch the next digit (4) from the dividend, attach it to 447 and continue: 4474 / 520

Moving on to step 8:
4474 divided by 520 is 8 with a remainder of 314.
The number 8 becomes the next digit in our result. 
Result so far: 129418.0
The remainder is 314 after subtracting 4160 from 4474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 9:
3140 divided by 520 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 129418.6
Subtracting 3120 from 3140 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
520 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 129418.6
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
2000 divided by 520 is 3 with a remainder of 440.
Write down 3 as next digit of the result. 
Result so far: 129418.603
If we subtract 1560 from 2000, we get 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.
Put 8 as the next digit of the answer. 
Result so far: 129418.6038
If we subtract 4160 from 4400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
520 can be fit into 2400 4 times, resulting in a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 129418.60384
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.

Let's proceed to step 14:
3200 divided by 520 is 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 129418.603846
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.

Going ahead to step 15:
The number 520 fits into 800 1 times, leaving a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 129418.6038461
If we subtract 520 from 800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
The next digit of our result is 5. 
Result so far: 129418.60384615
Subtract 2600 from 2800 to get 200.
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 129418.60384615 with a remainder of 2e-07.
