We're dividing 512134 by 17 
The aim is to understand the frequency of 17 in 512134.

Step 1:
If we divide 5 by 17, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 17

Step 2:
If we divide 51 by 17, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 51 from 51.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 17

On to step 3:
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: 30.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 17

Going ahead to step 4:
If we divide 21 by 17, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 301.0
The remainder is 4 after subtracting 17 from 21.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 17

Advancing to step 5:
If we divide 43 by 17, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 3012.0
If we subtract 34 from 43, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 17

Moving on to step 6:
When dividing 94 by 17, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 30125.0
Deduct 85 from 94 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 17, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 30125.5
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 30125.52
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 17 fits into 160 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 30125.529
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.

Step 10:
17 goes into 70 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 30125.5294
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 11:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 30125.52941
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.

Let's proceed to step 12:
When dividing 30 by 17, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 30125.529411
If we take 17 away from 30, we end up 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 outcome is 30125.529411, with a leftover of 1.3e-06.
