148245 ÷ 17 
The aim is to understand the frequency of 17 in 148245.

Let's proceed to step 1:
If we divide 1 by 17, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 17

Step 2:
17 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 17

Let's proceed to step 3:
The number 17 fits into 148 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 12 after subtracting 136 from 148.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 17

Moving on to step 4:
The number 17 fits into 122 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 119 from 122, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 17

Advancing to step 5:
34 divided by 17 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 872.0
Subtracting 34 from 34 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 17

Moving on to step 6:
If we divide 5 by 17, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 8720.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 17 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 8720.2
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 17 fits into 160 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 8720.29
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 17, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 8720.294
Subtracting 68 from 70 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8720.2941
If we take 17 away from 20, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 17 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 8720.29411
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 8720.29411 with a remainder of 1.3e-05.
