We look at the division of 34548921 by 510 
The aim is to understand the frequency of 510 in 34548921.

Advancing to step 1:
When dividing 3 by 510, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 510

Let's proceed to step 2:
When dividing 34 by 510, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 510

Step 3:
510 goes into 345 0 times with a remainder of 345.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 345 leaves us with 345.
Bring next digit (4) of the dividend behind the 345 and repeat the process: 3454 / 510

Moving on to step 4:
510 goes into 3454 6 times with a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 3060 away from 3454, we end up with 394.
Grab the next digit (8) from the dividend, add it to 394, then carry on: 3948 / 510

Going ahead to step 5:
510 goes into 3948 7 times with a remainder of 378.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we take 3570 away from 3948, we end up with 378.
Take the next digit (9) from the dividend and append it to 378, then repeat: 3789 / 510

Let's proceed to step 6:
3789 divided by 510 is 7 with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 677.0
Subtract 3570 from 3789 to get 219.
Grab the next digit (2) from the dividend, add it to 219, then carry on: 2192 / 510

On to step 7:
The number 510 fits into 2192 4 times, leaving a remainder of 152.
The next digit of our result is 4. 
Result so far: 6774.0
If we take 2040 away from 2192, we end up with 152.
Include the next digit (1) from the dividend after 152, then repeat: 1521 / 510

Let's proceed to step 8:
510 goes into 1521 2 times with a remainder of 501.
Use 2 as the next digit of our solution. 
Result so far: 67742.0
Subtract 1020 from 1521 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 9:
510 can be fit into 5010 9 times, resulting in a remainder of 420.
Put 9 as the next digit of the answer. 
Result so far: 67742.9
Deduct 4590 from 5010 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.

Step 10:
The number 510 fits into 4200 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 67742.98
If we take 4080 away from 4200, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
510 can be fit into 1200 2 times, resulting in a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 67742.982
Subtract 1020 from 1200 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
If we divide 1800 by 510, we get 3 and a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 67742.9823
If we take 1530 away from 1800, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 13:
If we divide 2700 by 510, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 67742.98235
Deduct 2550 from 2700 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
When dividing 1500 by 510, we get 2 with a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 67742.982352
Deduct 1020 from 1500 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 15:
If we divide 4800 by 510, we get 9 and a remainder of 210.
The next digit of our result is 9. 
Result so far: 67742.9823529
Subtract 4590 from 4800 to 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.

Step 16:
510 goes into 2100 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 67742.98235294
Subtracting 2040 from 2100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 67742.98235294 with a remaining 6e-08.
