We're dividing 401204 by 17 
The aim is to understand the frequency of 17 in 401204.

On to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 17

Let's proceed to step 2:
If we divide 40 by 17, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 34 away from 40, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 17

On to step 3:
If we divide 61 by 17, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 51 from 61 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 17

Advancing to step 4:
The number 17 fits into 102 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 236.0
The remainder is 0 after subtracting 102 from 102.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 17

Going ahead to step 5:
If we divide 0 by 17, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2360.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 17

Moving on to step 6:
If we divide 4 by 17, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 23600.0
Subtracting 0 from 4 leaves us 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.

Going ahead to step 7:
40 divided by 17 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 23600.2
If we take 34 away from 40, we end up 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.

Going ahead to step 8:
The number 17 fits into 60 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 23600.23
Subtracting 51 from 60 leaves us 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.

Let's proceed to step 9:
If we divide 90 by 17, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 23600.235
Subtracting 85 from 90 leaves us with 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 10:
The number 17 fits into 50 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 23600.2352
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.

On to step 11:
160 divided by 17 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 23600.23529
If we subtract 153 from 160, we 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.

Moving on to step 12:
When dividing 70 by 17, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 23600.235294
If we take 68 away from 70, we end up 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.

Let's proceed to step 13:
17 goes into 20 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 23600.2352941
If we take 17 away from 20, we end up 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.

On to step 14:
When dividing 30 by 17, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 23600.23529411
Deduct 17 from 30 and we're left 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.

After the division, we end up with 23600.23529411 and a remainder of 1.3e-08.
