We look at the division of 8152646 by 345 
The aim is to understand the frequency of 345 in 8152646.

Advancing to step 1:
345 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 345

Step 2:
345 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 345

Moving on to step 3:
345 can be fit into 815 2 times, resulting in a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 690 from 815, we get 125.
Append the next digit (2) from the dividend to 125 and continue with: 1252 / 345

Going ahead to step 4:
1252 divided by 345 is 3 with a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 1035 from 1252 leaves us with 217.
Include the next digit (6) from the dividend after 217, then repeat: 2176 / 345

On to step 5:
If we divide 2176 by 345, we get 6 and a remainder of 106.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
If we take 2070 away from 2176, we end up with 106.
Include the next digit (4) from the dividend after 106, then repeat: 1064 / 345

Let's proceed to step 6:
The number 345 fits into 1064 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 2363.0
Deduct 1035 from 1064 and we're left with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 345

Let's proceed to step 7:
345 can be fit into 296 0 times, resulting in a remainder of 296.
Record the quotient 0 as the next digit in the result. 
Result so far: 23630.0
Subtracting 0 from 296 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 8:
When dividing 2960 by 345, we get 8 with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 23630.8
Deduct 2760 from 2960 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
345 goes into 2000 5 times with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 23630.85
If we subtract 1725 from 2000, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
If we divide 2750 by 345, we get 7 and a remainder of 335.
The next digit of our result is 7. 
Result so far: 23630.857
If we subtract 2415 from 2750, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 11:
The number 345 fits into 3350 9 times, leaving a remainder of 245.
Record the quotient 9 as the next digit in the result. 
Result so far: 23630.8579
The remainder is 245 after subtracting 3105 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 12:
The number 345 fits into 2450 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 23630.85797
Subtracting 2415 from 2450 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
The number 345 fits into 350 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 23630.857971
Subtracting 345 from 350 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
345 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 23630.857971
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
When dividing 500 by 345, we get 1 with a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 23630.85797101
Subtracting 345 from 500 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 23630.85797101, with a leftover of 1.55e-07.
