67076412 ÷ 520 
The aim is to understand the frequency of 520 in 67076412.

Moving on to step 1:
The number 520 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 520

Step 2:
520 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 520

Let's proceed to step 3:
If we divide 670 by 520, we get 1 and a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 520 away from 670, we end up with 150.
Take the next digit (7) from the dividend and append it to 150, then repeat: 1507 / 520

On to step 4:
520 goes into 1507 2 times with a remainder of 467.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1040 from 1507 leaves us with 467.
Grab the next digit (6) from the dividend, add it to 467, then carry on: 4676 / 520

Going ahead to step 5:
When dividing 4676 by 520, we get 8 with a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 128.0
The remainder is 516 after subtracting 4160 from 4676.
Take the next digit (4) from the dividend and append it to 516, then repeat: 5164 / 520

Advancing to step 6:
If we divide 5164 by 520, we get 9 and a remainder of 484.
Record the quotient 9 as the next digit in the result. 
Result so far: 1289.0
Deduct 4680 from 5164 and we're left with 484.
Fetch the next digit (1) from the dividend, attach it to 484 and continue: 4841 / 520

Advancing to step 7:
520 goes into 4841 9 times with a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 12899.0
If we take 4680 away from 4841, we end up with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 520

Moving on to step 8:
520 goes into 1612 3 times with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 128993.0
Subtract 1560 from 1612 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
520 goes into 520 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 128993.1
Subtracting 520 from 520 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 520, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128993.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 520 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128993.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 128993.1, with a leftover of 0.0.
