996580 divided by 17 
The aim is to understand the frequency of 17 in 996580.

Step 1:
17 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 17

Advancing to step 2:
If we divide 99 by 17, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 85 from 99 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 17

Let's proceed to step 3:
17 can be fit into 146 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 136 from 146 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 17

On to step 4:
17 goes into 105 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 586.0
Subtracting 102 from 105 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 17

Let's proceed to step 5:
17 can be fit into 38 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 5862.0
The remainder is 4 after subtracting 34 from 38.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 17

Going ahead to step 6:
The number 17 fits into 40 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 58622.0
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 17, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 58622.3
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
The number 17 fits into 90 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 58622.35
If we subtract 85 from 90, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 58622.352
Subtract 34 from 50 to 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.

Going ahead to step 10:
17 goes into 160 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 58622.3529
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 11:
If we divide 70 by 17, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 58622.35294
Deduct 68 from 70 and we're left 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.

On to step 12:
20 divided by 17 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 58622.352941
Subtracting 17 from 20 leaves us with 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 13:
When dividing 30 by 17, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 58622.3529411
If we take 17 away from 30, we end up 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.

The final outcome is 58622.3529411, with a leftover of 1.3e-07.
