We're dividing 257464 by 17 
The aim is to understand the frequency of 17 in 257464.

Moving on to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 17

Let's proceed to step 2:
If we divide 25 by 17, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 17 from 25 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 17

Step 3:
87 divided by 17 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 2 after subtracting 85 from 87.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 17

Advancing to step 4:
When dividing 24 by 17, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 17 from 24 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 17

On to step 5:
If we divide 76 by 17, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1514.0
Subtracting 68 from 76 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 17

Moving on to step 6:
If we divide 84 by 17, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 15144.0
If we take 68 away from 84, we end up 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.

Let's proceed to step 7:
If we divide 160 by 17, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 15144.9
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
17 goes into 70 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 15144.94
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
When dividing 20 by 17, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 15144.941
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
30 divided by 17 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 15144.9411
Subtracting 17 from 30 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.

The final result is 15144.9411 with a remainder of 0.00013.
