383957 ÷ 17 
The aim is to understand the frequency of 17 in 383957.

On to step 1:
17 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 17

Step 2:
If we divide 38 by 17, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 34 from 38 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 17

Step 3:
17 can be fit into 43 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 34 from 43 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 17

Moving on to step 4:
If we divide 99 by 17, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Subtract 85 from 99 to get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 17

Moving on to step 5:
If we divide 145 by 17, we get 8 and a remainder of 9.
The next digit of our result is 8. 
Result so far: 2258.0
If we take 136 away from 145, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 17

Moving on to step 6:
97 divided by 17 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 22585.0
If we take 85 away from 97, 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.

Advancing to step 7:
120 divided by 17 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 22585.7
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
10 divided by 17 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22585.7
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.

Let's proceed to step 9:
When dividing 100 by 17, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22585.705
If we take 85 away from 100, we end up 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 10:
When dividing 150 by 17, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 22585.7058
If we take 136 away from 150, we end up 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.

Let's proceed to step 11:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 22585.70588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 22585.70588 with a remaining 4e-06.
