366440 ÷ 17 
The aim is to understand the frequency of 17 in 366440.

Moving on to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 17

Advancing to step 2:
36 divided by 17 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 34 from 36 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 17

On to step 3:
26 divided by 17 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 9 after subtracting 17 from 26.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 17

Moving on to step 4:
17 goes into 94 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtract 85 from 94 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 17

Moving on to step 5:
17 can be fit into 94 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 2155.0
Subtracting 85 from 94 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 17

On to step 6:
If we divide 90 by 17, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 21555.0
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 7:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 21555.2
Subtracting 34 from 50 leaves us 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.

Advancing to step 8:
If we divide 160 by 17, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 21555.29
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 17 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 21555.294
Subtracting 68 from 70 leaves us 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 10:
If we divide 20 by 17, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21555.2941
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.

Going ahead to step 11:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 21555.29411
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.

Our division results in 21555.29411 with a remaining 1.3e-05.
