We look at the division of 51024 by 17 
The aim is to understand the frequency of 17 in 51024.

Going ahead to step 1:
17 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 17

On to step 2:
If we divide 51 by 17, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 51 away from 51, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 17

On to step 3:
17 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 17

Going ahead to step 4:
If we divide 2 by 17, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 17

On to step 5:
17 can be fit into 24 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 3001.0
Subtracting 17 from 24 leaves us 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 6:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3001.4
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 17 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 3001.41
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.

On to step 8:
17 goes into 30 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 3001.411
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 3001.411 with a remaining 0.0013.
