We're dividing 231269 by 17 
The aim is to understand the frequency of 17 in 231269.

Advancing to step 1:
2 divided by 17 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 17

Step 2:
The number 17 fits into 23 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 6 after subtracting 17 from 23.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 17

Moving on to step 3:
17 can be fit into 61 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 51 from 61 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 17

Going ahead to step 4:
If we divide 102 by 17, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 136.0
If we take 102 away from 102, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 17

Let's proceed to step 5:
17 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 1360.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 17

Let's proceed to step 6:
When dividing 69 by 17, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 13604.0
Deduct 68 from 69 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.

Going ahead to step 7:
If we divide 10 by 17, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13604.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13604.05
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 9:
150 divided by 17 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 13604.058
Subtracting 136 from 150 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
140 divided by 17 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 13604.0588
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.

After the division, we end up with 13604.0588 and a remainder of 4e-05.
