529081 ÷ 17 
The aim is to understand the frequency of 17 in 529081.

Step 1:
The number 17 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 17

Going ahead to step 2:
The number 17 fits into 52 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 51 from 52 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 17

Step 3:
When dividing 19 by 17, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 17 from 19 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 17

Advancing to step 4:
If we divide 20 by 17, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtract 17 from 20 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 17

Moving on to step 5:
The number 17 fits into 38 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3112.0
Deduct 34 from 38 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 17

Moving on to step 6:
41 divided by 17 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 31122.0
Deduct 34 from 41 and we're left with 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 7:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 31122.4
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 8:
17 goes into 20 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 31122.41
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.

Advancing to step 9:
30 divided by 17 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31122.411
Subtracting 17 from 30 leaves us 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 31122.411 and a remainder of 0.0013.
