We look at the division of 17305396 by 439 
The aim is to understand the frequency of 439 in 17305396.

On to step 1:
If we divide 1 by 439, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 439

On to step 2:
The number 439 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 439

Advancing to step 3:
The number 439 fits into 173 0 times, leaving a remainder of 173.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 173 to get 173.
Grab the next digit (0) from the dividend, add it to 173, then carry on: 1730 / 439

Let's proceed to step 4:
439 can be fit into 1730 3 times, resulting in a remainder of 413.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1317 away from 1730, we end up with 413.
Take the next digit (5) from the dividend and append it to 413, then repeat: 4135 / 439

Advancing to step 5:
439 can be fit into 4135 9 times, resulting in a remainder of 184.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 3951 from 4135, we get 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 439

Step 6:
When dividing 1843 by 439, we get 4 with a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 394.0
Subtracting 1756 from 1843 leaves us with 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 439

Moving on to step 7:
When dividing 879 by 439, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 3942.0
Subtract 878 from 879 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 439

On to step 8:
The number 439 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 39420.0
Subtracting 0 from 16 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.

Let's proceed to step 9:
When dividing 160 by 439, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 39420.0
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
439 goes into 1600 3 times with a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 39420.03
If we subtract 1317 from 1600, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 11:
If we divide 2830 by 439, we get 6 and a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 39420.036
If we subtract 2634 from 2830, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
439 goes into 1960 4 times with a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 39420.0364
Deduct 1756 from 1960 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 13:
439 goes into 2040 4 times with a remainder of 284.
The next digit of our result is 4. 
Result so far: 39420.03644
If we subtract 1756 from 2040, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 39420.03644 with a balance of 0.000284.
