65424156 divided by 345 
The aim is to understand the frequency of 345 in 65424156.

Going ahead to step 1:
345 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 345

Moving on to step 2:
The number 345 fits into 65 0 times, leaving a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 345

Going ahead to step 3:
345 goes into 654 1 times with a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 309 after subtracting 345 from 654.
Include the next digit (2) from the dividend after 309, then repeat: 3092 / 345

Going ahead to step 4:
If we divide 3092 by 345, we get 8 and a remainder of 332.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 2760 from 3092, we get 332.
Bring next digit (4) of the dividend behind the 332 and repeat the process: 3324 / 345

Step 5:
345 can be fit into 3324 9 times, resulting in a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 189.0
The remainder is 219 after subtracting 3105 from 3324.
Bring next digit (1) of the dividend behind the 219 and repeat the process: 2191 / 345

Step 6:
The number 345 fits into 2191 6 times, leaving a remainder of 121.
Record the quotient 6 as the next digit in the result. 
Result so far: 1896.0
Subtracting 2070 from 2191 leaves us with 121.
Fetch the next digit (5) from the dividend, attach it to 121 and continue: 1215 / 345

Advancing to step 7:
1215 divided by 345 is 3 with a remainder of 180.
Put 3 as the next digit of the answer. 
Result so far: 18963.0
Subtracting 1035 from 1215 leaves us with 180.
Take the next digit (6) from the dividend and append it to 180, then repeat: 1806 / 345

Moving on to step 8:
The number 345 fits into 1806 5 times, leaving a remainder of 81.
The next digit of our result is 5. 
Result so far: 189635.0
Subtract 1725 from 1806 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
345 can be fit into 810 2 times, resulting in a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 189635.2
Subtracting 690 from 810 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.

Moving on to step 10:
345 goes into 1200 3 times with a remainder of 165.
The next digit of our result is 3. 
Result so far: 189635.23
Deduct 1035 from 1200 and we're left with 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 11:
When dividing 1650 by 345, we get 4 with a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 189635.234
The remainder is 270 after subtracting 1380 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 12:
2700 divided by 345 is 7 with a remainder of 285.
Use 7 as the next digit of our solution. 
Result so far: 189635.2347
Deduct 2415 from 2700 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 13:
345 can be fit into 2850 8 times, resulting in a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 189635.23478
Subtract 2760 from 2850 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 14:
When dividing 900 by 345, we get 2 with a remainder of 210.
The next digit of our result is 2. 
Result so far: 189635.234782
If we subtract 690 from 900, we 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.

Advancing to step 15:
When dividing 2100 by 345, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 189635.2347826
If we subtract 2070 from 2100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 16:
If we divide 300 by 345, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 189635.2347826
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 189635.2347826 and a remainder of 3e-07.
