565997 ÷ 17 
The aim is to understand the frequency of 17 in 565997.

Moving on to step 1:
When dividing 5 by 17, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 17

Moving on to step 2:
The number 17 fits into 56 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 51 from 56 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 17

Let's proceed to step 3:
55 divided by 17 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 51 away from 55, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 17

On to step 4:
17 can be fit into 49 2 times, resulting in a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 332.0
Deduct 34 from 49 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 17

Let's proceed to step 5:
The number 17 fits into 159 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 3329.0
If we take 153 away from 159, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 17

Step 6:
17 goes into 67 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 33293.0
If we subtract 51 from 67, we 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.

Step 7:
160 divided by 17 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 33293.9
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 8:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 33293.94
If we take 68 away from 70, we end up 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.

Advancing to step 9:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 33293.941
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
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: 33293.9411
Subtract 17 from 30 to 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.

The final outcome is 33293.9411, with a leftover of 0.00013.
