Let's divide 444621 by 17
The aim is to understand the frequency of 17 in 444621.

On to step 1:
When dividing 4 by 17, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 17

Moving on to step 2:
44 divided by 17 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 34 away from 44, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 17

On to step 3:
17 can be fit into 104 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 2 after subtracting 102 from 104.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 17

Going ahead to step 4:
When dividing 26 by 17, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 261.0
If we take 17 away from 26, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 17

On to step 5:
17 goes into 92 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 2615.0
The remainder is 7 after subtracting 85 from 92.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 17

On to step 6:
The number 17 fits into 71 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 26154.0
Deduct 68 from 71 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.

Let's proceed to step 7:
When dividing 30 by 17, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 26154.1
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.

Step 8:
The number 17 fits into 130 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 26154.17
Deduct 119 from 130 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
If we divide 110 by 17, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 26154.176
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
80 divided by 17 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 26154.1764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 26154.17647
The remainder is 1 after subtracting 119 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 17, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 26154.17647
If we take 0 away from 10, we end up 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.

On to step 13:
17 goes into 100 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 26154.1764705
Subtracting 85 from 100 leaves us 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.

On to step 14:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 26154.17647058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 26154.17647058 with a remaining 1.4e-08.
