We look at the division of 68476908 by 345 
The aim is to understand the frequency of 345 in 68476908.

Advancing to step 1:
345 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 345

Let's proceed to step 2:
345 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 345

On to step 3:
684 divided by 345 is 1 with a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 339 after subtracting 345 from 684.
Append the next digit (7) from the dividend to 339 and continue with: 3397 / 345

Step 4:
3397 divided by 345 is 9 with a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 3105 from 3397 and we're left with 292.
Append the next digit (6) from the dividend to 292 and continue with: 2926 / 345

On to step 5:
The number 345 fits into 2926 8 times, leaving a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we subtract 2760 from 2926, we get 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 345

Moving on to step 6:
1669 divided by 345 is 4 with a remainder of 289.
Put 4 as the next digit of the answer. 
Result so far: 1984.0
Deduct 1380 from 1669 and we're left with 289.
Grab the next digit (0) from the dividend, add it to 289, then carry on: 2890 / 345

Let's proceed to step 7:
When dividing 2890 by 345, we get 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 19848.0
If we subtract 2760 from 2890, we get 130.
Append the next digit (8) from the dividend to 130 and continue with: 1308 / 345

Advancing to step 8:
The number 345 fits into 1308 3 times, leaving a remainder of 273.
Write down 3 as next digit of the result. 
Result so far: 198483.0
Deduct 1035 from 1308 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 9:
When dividing 2730 by 345, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 198483.7
If we subtract 2415 from 2730, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 10:
When dividing 3150 by 345, we get 9 with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 198483.79
Subtracting 3105 from 3150 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
If we divide 450 by 345, we get 1 and a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 198483.791
If we take 345 away from 450, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 12:
The number 345 fits into 1050 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 198483.7913
Deduct 1035 from 1050 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
345 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 198483.7913
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
345 can be fit into 1500 4 times, resulting in a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 198483.791304
If we subtract 1380 from 1500, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
1200 divided by 345 is 3 with a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 198483.7913043
Subtract 1035 from 1200 to 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.

On to step 16:
345 goes into 1650 4 times with a remainder of 270.
Put 4 as the next digit of the answer. 
Result so far: 198483.79130434
If we subtract 1380 from 1650, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 198483.79130434 with a remainder of 2.7e-07.
