We divide 453923 by 17
The aim is to understand the frequency of 17 in 453923.

Advancing to step 1:
The number 17 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 17

Going ahead to step 2:
17 can be fit into 45 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 34 away from 45, we end up with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 17

Going ahead to step 3:
17 can be fit into 113 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we subtract 102 from 113, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 17

Advancing to step 4:
If we divide 119 by 17, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
The remainder is 0 after subtracting 119 from 119.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 17

Going ahead to step 5:
2 divided by 17 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 2670.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 17

Going ahead to step 6:
When dividing 23 by 17, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 26701.0
If we subtract 17 from 23, we get 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 can be fit into 60 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 26701.3
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.

Moving on to step 8:
When dividing 90 by 17, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 26701.35
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.

Let's proceed to step 9:
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: 26701.352
If we subtract 34 from 50, we 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.

Step 10:
If we divide 160 by 17, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 26701.3529
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: 26701.35294
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.

Step 12:
17 goes into 20 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 26701.352941
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:
30 divided by 17 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 26701.3529411
If we subtract 17 from 30, we 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.

After the division, we end up with 26701.3529411 and a remainder of 1.3e-07.
