We're dividing 450319 by 17 
The aim is to understand the frequency of 17 in 450319.

Let's proceed to step 1:
4 divided by 17 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 17

On to step 2:
When dividing 45 by 17, we get 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 34 away from 45, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 17

Going ahead to step 3:
When dividing 110 by 17, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 102 from 110 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 17

Advancing to step 4:
17 can be fit into 83 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 264.0
Subtracting 68 from 83 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 17

On to step 5:
151 divided by 17 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 2648.0
Deduct 136 from 151 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 17

Going ahead to step 6:
159 divided by 17 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 26489.0
Subtracting 153 from 159 leaves us 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.

On to step 7:
17 goes into 60 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 26489.3
If we subtract 51 from 60, we 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.

Going ahead to step 8:
17 can be fit into 90 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 26489.35
Subtract 85 from 90 to 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.

Going ahead to step 9:
When dividing 50 by 17, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 26489.352
If we take 34 away from 50, we end up with 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:
160 divided by 17 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 26489.3529
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.

Moving on to step 11:
70 divided by 17 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 26489.35294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 26489.352941
Deduct 17 from 20 and we're left 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:
17 goes into 30 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 26489.3529411
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.

The quotient of the division is 26489.3529411, and the remainder is 1.3e-07.
