We look at the division of 82621602 by 345 
The aim is to understand the frequency of 345 in 82621602.

Going ahead to step 1:
When dividing 8 by 345, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 345

Let's proceed to step 2:
If we divide 82 by 345, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (6) of the dividend behind the 82 and repeat the process: 826 / 345

Let's proceed to step 3:
826 divided by 345 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 690 from 826 and we're left with 136.
Include the next digit (2) from the dividend after 136, then repeat: 1362 / 345

Moving on to step 4:
When dividing 1362 by 345, we get 3 with a remainder of 327.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1035 from 1362 leaves us with 327.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 345

On to step 5:
The number 345 fits into 3271 9 times, leaving a remainder of 166.
The next digit of our result is 9. 
Result so far: 239.0
Deduct 3105 from 3271 and we're left with 166.
Take the next digit (6) from the dividend and append it to 166, then repeat: 1666 / 345

Going ahead to step 6:
1666 divided by 345 is 4 with a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 2394.0
The remainder is 286 after subtracting 1380 from 1666.
Bring next digit (0) of the dividend behind the 286 and repeat the process: 2860 / 345

Moving on to step 7:
The number 345 fits into 2860 8 times, leaving a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 23948.0
The remainder is 100 after subtracting 2760 from 2860.
Fetch the next digit (2) from the dividend, attach it to 100 and continue: 1002 / 345

Moving on to step 8:
When dividing 1002 by 345, we get 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 239482.0
If we subtract 690 from 1002, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 9:
345 can be fit into 3120 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 239482.9
Subtract 3105 from 3120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 345 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 239482.9
Subtracting 0 from 150 leaves us 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.

Step 11:
The number 345 fits into 1500 4 times, leaving a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 239482.904
Subtracting 1380 from 1500 leaves us 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.

On to step 12:
If we divide 1200 by 345, we get 3 and a remainder of 165.
Record the quotient 3 as the next digit in the result. 
Result so far: 239482.9043
If we subtract 1035 from 1200, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
345 goes into 1650 4 times with a remainder of 270.
The next digit of our result is 4. 
Result so far: 239482.90434
Subtracting 1380 from 1650 leaves us 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.

Let's proceed to step 14:
345 can be fit into 2700 7 times, resulting in a remainder of 285.
Write down 7 as next digit of the result. 
Result so far: 239482.904347
The remainder is 285 after subtracting 2415 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 15:
2850 divided by 345 is 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 239482.9043478
If we take 2760 away from 2850, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
900 divided by 345 is 2 with a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 239482.90434782
The remainder is 210 after subtracting 690 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

After the division, we end up with 239482.90434782 and a remainder of 2.1e-07.
