We're dividing 212913 by 17 
The aim is to understand the frequency of 17 in 212913.

Going ahead to step 1:
17 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 17

Going ahead to step 2:
17 goes into 21 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 17 from 21, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

Moving on to step 3:
17 goes into 42 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 34 from 42 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 17

Let's proceed to step 4:
17 goes into 89 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 85 from 89 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 17

Step 5:
When dividing 41 by 17, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
The remainder is 7 after subtracting 34 from 41.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 17

Going ahead to step 6:
The number 17 fits into 73 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 12524.0
Subtracting 68 from 73 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.

Let's proceed to step 7:
17 goes into 50 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12524.2
Subtracting 34 from 50 leaves us 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.

Advancing to step 8:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 12524.29
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.

Moving on to step 9:
When dividing 70 by 17, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 12524.294
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.

On to step 10:
If we divide 20 by 17, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 12524.2941
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.

Moving on to step 11:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 12524.29411
Deduct 17 from 30 and we're left 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.

After the division, we end up with 12524.29411 and a remainder of 1.3e-05.
