We look at the division of 68671947 by 510 
The aim is to understand the frequency of 510 in 68671947.

On to step 1:
If we divide 6 by 510, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 510

On to step 2:
When dividing 68 by 510, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 510

Moving on to step 3:
If we divide 686 by 510, we get 1 and a remainder of 176.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 510 from 686 to get 176.
Bring next digit (7) of the dividend behind the 176 and repeat the process: 1767 / 510

Moving on to step 4:
If we divide 1767 by 510, we get 3 and a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 237 after subtracting 1530 from 1767.
Fetch the next digit (1) from the dividend, attach it to 237 and continue: 2371 / 510

Advancing to step 5:
510 goes into 2371 4 times with a remainder of 331.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we take 2040 away from 2371, we end up with 331.
Take the next digit (9) from the dividend and append it to 331, then repeat: 3319 / 510

On to step 6:
3319 divided by 510 is 6 with a remainder of 259.
Use 6 as the next digit of our solution. 
Result so far: 1346.0
Subtract 3060 from 3319 to get 259.
Include the next digit (4) from the dividend after 259, then repeat: 2594 / 510

On to step 7:
If we divide 2594 by 510, we get 5 and a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 13465.0
Subtract 2550 from 2594 to get 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 510

Moving on to step 8:
The number 510 fits into 447 0 times, leaving a remainder of 447.
Write down 0 as next digit of the result. 
Result so far: 134650.0
Subtracting 0 from 447 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Let's proceed to step 9:
510 can be fit into 4470 8 times, resulting in a remainder of 390.
Record the quotient 8 as the next digit in the result. 
Result so far: 134650.8
If we take 4080 away from 4470, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
If we divide 3900 by 510, we get 7 and a remainder of 330.
The number 7 becomes the next digit in our result. 
Result so far: 134650.87
Subtract 3570 from 3900 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
The number 510 fits into 3300 6 times, leaving a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 134650.876
Subtract 3060 from 3300 to 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.

Advancing to step 12:
510 goes into 2400 4 times with a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 134650.8764
If we take 2040 away from 2400, we end up 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.

Going ahead to step 13:
The number 510 fits into 3600 7 times, leaving a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 134650.87647
Subtracting 3570 from 3600 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
510 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 134650.87647
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
510 goes into 3000 5 times with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 134650.8764705
Subtracting 2550 from 3000 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 16:
The number 510 fits into 4500 8 times, leaving a remainder of 420.
The next digit of our result is 8. 
Result so far: 134650.87647058
Deduct 4080 from 4500 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 134650.87647058 with a balance of 4.2e-07.
