We divide 16887181 by 510
The aim is to understand the frequency of 510 in 16887181.

Moving on to step 1:
510 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 510

Advancing to step 2:
When dividing 16 by 510, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 510

On to step 3:
168 divided by 510 is 0 with a remainder of 168.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 168 after subtracting 0 from 168.
Fetch the next digit (8) from the dividend, attach it to 168 and continue: 1688 / 510

On to step 4:
If we divide 1688 by 510, we get 3 and a remainder of 158.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1530 from 1688 leaves us with 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 510

Step 5:
The number 510 fits into 1587 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 1530 from 1587, we get 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 510

Let's proceed to step 6:
510 can be fit into 571 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 331.0
Subtract 510 from 571 to get 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 510

On to step 7:
The number 510 fits into 618 1 times, leaving a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 3311.0
If we subtract 510 from 618, we get 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 510

Step 8:
1081 divided by 510 is 2 with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 33112.0
Subtract 1020 from 1081 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
510 goes into 610 1 times with a remainder of 100.
The next digit of our result is 1. 
Result so far: 33112.1
Deduct 510 from 610 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
510 goes into 1000 1 times with a remainder of 490.
Use 1 as the next digit of our solution. 
Result so far: 33112.11
If we take 510 away from 1000, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

After the division, we end up with 33112.11 and a remainder of 0.49.
