We divide 620339 by 17
The aim is to understand the frequency of 17 in 620339.

Going ahead to step 1:
6 divided by 17 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 17

Step 2:
17 goes into 62 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 51 from 62 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 17

On to step 3:
When dividing 110 by 17, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Deduct 102 from 110 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 17

Going ahead to step 4:
17 goes into 83 4 times with a remainder of 15.
The next digit of our result is 4. 
Result so far: 364.0
If we subtract 68 from 83, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 17

Let's proceed to step 5:
The number 17 fits into 153 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3649.0
Subtracting 153 from 153 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 17

Step 6:
17 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 36490.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 17, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 36490.5
Deduct 85 from 90 and we're left 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.

Going ahead to step 8:
If we divide 50 by 17, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 36490.52
The remainder is 16 after subtracting 34 from 50.
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 9:
160 divided by 17 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 36490.529
If we take 153 away from 160, we end up 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.

Going ahead to step 10:
If we divide 70 by 17, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 36490.5294
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.

Let's proceed to step 11:
20 divided by 17 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 36490.52941
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.

Step 12:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 36490.529411
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 result is 36490.529411 with a remainder of 1.3e-06.
