We're dividing 669302 by 17 
The aim is to understand the frequency of 17 in 669302.

Going ahead to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 17

On to step 2:
The number 17 fits into 66 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 51 from 66 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 17

Going ahead to step 3:
When dividing 159 by 17, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 153 away from 159, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Step 4:
63 divided by 17 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Subtracting 51 from 63 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 17

Moving on to step 5:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 3937.0
Subtracting 119 from 120 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 17

On to step 6:
17 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 39370.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 17 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 39370.7
If we take 119 away from 120, we end up 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.

Advancing to step 8:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 39370.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 17, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 39370.705
If we take 85 away from 100, we end up 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.

Going ahead to step 10:
If we divide 150 by 17, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 39370.7058
Subtract 136 from 150 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.

On to step 11:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 39370.70588
Subtracting 136 from 140 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 39370.70588 with a remaining 4e-06.
