353495 divided by 17 
The aim is to understand the frequency of 17 in 353495.

Step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 17

On to step 2:
17 goes into 35 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 34 from 35.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 17

Advancing to step 3:
17 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 13, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 17

Advancing to step 4:
134 divided by 17 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
The remainder is 15 after subtracting 119 from 134.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 17

Going ahead to step 5:
159 divided by 17 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2079.0
Deduct 153 from 159 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 17

Let's proceed to step 6:
17 can be fit into 65 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 20793.0
Subtract 51 from 65 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
17 goes into 140 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 20793.8
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 17, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 20793.82
If we take 34 away from 40, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 17 fits into 60 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 20793.823
If we take 51 away from 60, we end up 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.

Going ahead to step 10:
When dividing 90 by 17, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 20793.8235
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.

On to step 11:
17 can be fit into 50 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 20793.82352
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.

On to step 12:
160 divided by 17 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 20793.823529
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.

Going ahead to step 13:
17 goes into 70 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 20793.8235294
If we subtract 68 from 70, we 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.

Advancing to step 14:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 20793.82352941
Subtract 17 from 20 to 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.

Our division results in 20793.82352941 with a remaining 3e-09.
