30686088 ÷ 510 
The aim is to understand the frequency of 510 in 30686088.

Step 1:
If we divide 3 by 510, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 510

Advancing to step 2:
30 divided by 510 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 510

Advancing to step 3:
If we divide 306 by 510, we get 0 and a remainder of 306.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Fetch the next digit (8) from the dividend, attach it to 306 and continue: 3068 / 510

Advancing to step 4:
510 goes into 3068 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 3060 away from 3068, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 510

Step 5:
When dividing 86 by 510, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 510

On to step 6:
510 can be fit into 860 1 times, resulting in a remainder of 350.
The next digit of our result is 1. 
Result so far: 601.0
Deduct 510 from 860 and we're left with 350.
Fetch the next digit (8) from the dividend, attach it to 350 and continue: 3508 / 510

Going ahead to step 7:
510 can be fit into 3508 6 times, resulting in a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 6016.0
If we subtract 3060 from 3508, we get 448.
Bring next digit (8) of the dividend behind the 448 and repeat the process: 4488 / 510

On to step 8:
When dividing 4488 by 510, we get 8 with a remainder of 408.
The next digit of our result is 8. 
Result so far: 60168.0
Subtract 4080 from 4488 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
The number 510 fits into 4080 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 60168.8
Deduct 4080 from 4080 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.

Let's proceed to step 10:
510 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60168.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 510 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 60168.8
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 60168.8 with a balance of 0.0.
