We look at the division of 429185 by 17 
The aim is to understand the frequency of 17 in 429185.

Step 1:
4 divided by 17 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

Advancing to step 2:
If we divide 42 by 17, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 34 from 42 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 17

Moving on to step 3:
The number 17 fits into 89 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 85 from 89 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 17

Advancing to step 4:
17 goes into 41 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
If we take 34 away from 41, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 17

Step 5:
When dividing 78 by 17, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 2524.0
If we take 68 away from 78, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 17

Let's proceed to step 6:
When dividing 105 by 17, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 25246.0
If we take 102 away from 105, 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 7:
17 goes into 30 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 25246.1
If we subtract 17 from 30, we 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.

Let's proceed to step 8:
17 can be fit into 130 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 25246.17
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 17 fits into 110 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 25246.176
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.

Moving on to step 10:
17 goes into 80 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 25246.1764
Deduct 68 from 80 and we're left 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.

Step 11:
120 divided by 17 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 25246.17647
Deduct 119 from 120 and we're left 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.

Let's proceed to step 12:
If we divide 10 by 17, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 25246.17647
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 25246.1764705
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
17 goes into 150 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 25246.17647058
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 25246.17647058 and a remainder of 1.4e-08.
