40012047 divided by 510 
The aim is to understand the frequency of 510 in 40012047.

Advancing to step 1:
510 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 510

Moving on to step 2:
When dividing 40 by 510, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 510

Step 3:
400 divided by 510 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 400 after subtracting 0 from 400.
Take the next digit (1) from the dividend and append it to 400, then repeat: 4001 / 510

On to step 4:
510 can be fit into 4001 7 times, resulting in a remainder of 431.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 3570 away from 4001, we end up with 431.
Include the next digit (2) from the dividend after 431, then repeat: 4312 / 510

Let's proceed to step 5:
The number 510 fits into 4312 8 times, leaving a remainder of 232.
The next digit of our result is 8. 
Result so far: 78.0
If we take 4080 away from 4312, we end up with 232.
Append the next digit (0) from the dividend to 232 and continue with: 2320 / 510

Let's proceed to step 6:
When dividing 2320 by 510, we get 4 with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 784.0
Subtracting 2040 from 2320 leaves us with 280.
Fetch the next digit (4) from the dividend, attach it to 280 and continue: 2804 / 510

Step 7:
When dividing 2804 by 510, we get 5 with a remainder of 254.
The number 5 becomes the next digit in our result. 
Result so far: 7845.0
The remainder is 254 after subtracting 2550 from 2804.
Fetch the next digit (7) from the dividend, attach it to 254 and continue: 2547 / 510

On to step 8:
If we divide 2547 by 510, we get 4 and a remainder of 507.
Write down 4 as next digit of the result. 
Result so far: 78454.0
Subtracting 2040 from 2547 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Step 9:
510 goes into 5070 9 times with a remainder of 480.
Put 9 as the next digit of the answer. 
Result so far: 78454.9
If we subtract 4590 from 5070, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
If we divide 4800 by 510, we get 9 and a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 78454.99
If we subtract 4590 from 4800, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 78454.99 with a remainder of 0.21.
