We look at the division of 17204 by 424 
The aim is to understand the frequency of 424 in 17204.

Going ahead to step 1:
424 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 424

Step 2:
17 divided by 424 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 424

Advancing to step 3:
If we divide 172 by 424, we get 0 and a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 172 to get 172.
Grab the next digit (0) from the dividend, add it to 172, then carry on: 1720 / 424

Going ahead to step 4:
424 can be fit into 1720 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 24 after subtracting 1696 from 1720.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 424

Let's proceed to step 5:
244 divided by 424 is 0 with a remainder of 244.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 244 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 6:
424 goes into 2440 5 times with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 40.5
Subtract 2120 from 2440 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 7:
When dividing 3200 by 424, we get 7 with a remainder of 232.
Put 7 as the next digit of the answer. 
Result so far: 40.57
Subtract 2968 from 3200 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 8:
If we divide 2320 by 424, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 40.575
Subtract 2120 from 2320 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 9:
When dividing 2000 by 424, we get 4 with a remainder of 304.
The next digit of our result is 4. 
Result so far: 40.5754
If we subtract 1696 from 2000, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 10:
424 goes into 3040 7 times with a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 40.57547
Deduct 2968 from 3040 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
When dividing 720 by 424, we get 1 with a remainder of 296.
Record the quotient 1 as the next digit in the result. 
Result so far: 40.575471
Deduct 424 from 720 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 12:
The number 424 fits into 2960 6 times, leaving a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 40.5754716
Subtracting 2544 from 2960 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
4160 divided by 424 is 9 with a remainder of 344.
Write down 9 as next digit of the result. 
Result so far: 40.57547169
Deduct 3816 from 4160 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final result is 40.57547169 with a remainder of 3.44e-07.
