We look at the division of 386848 by 17 
The aim is to understand the frequency of 17 in 386848.

Let's proceed to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 17

Going ahead to step 2:
38 divided by 17 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 34 away from 38, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 17

Advancing to step 3:
46 divided by 17 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 34 from 46, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 17

Moving on to step 4:
The number 17 fits into 128 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 227.0
If we subtract 119 from 128, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 17

Moving on to step 5:
If we divide 94 by 17, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 2275.0
If we subtract 85 from 94, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 17

On to step 6:
The number 17 fits into 98 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 22755.0
Subtracting 85 from 98 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
The number 17 fits into 130 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 22755.7
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
17 goes into 110 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 22755.76
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 17, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 22755.764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
If we divide 120 by 17, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 22755.7647
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22755.7647
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
17 goes into 100 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 22755.764705
If we subtract 85 from 100, we 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.

On to step 13:
150 divided by 17 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 22755.7647058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
If we divide 140 by 17, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 22755.76470588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 22755.76470588 with a balance of 4e-09.
