We look at the division of 98368349 by 409 
The aim is to understand the frequency of 409 in 98368349.

On to step 1:
409 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 409

Advancing to step 2:
If we divide 98 by 409, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 409

Going ahead to step 3:
The number 409 fits into 983 2 times, leaving a remainder of 165.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 818 from 983 and we're left with 165.
Take the next digit (6) from the dividend and append it to 165, then repeat: 1656 / 409

Step 4:
1656 divided by 409 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 1636 away from 1656, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 409

Step 5:
The number 409 fits into 208 0 times, leaving a remainder of 208.
Write down 0 as next digit of the result. 
Result so far: 240.0
If we subtract 0 from 208, we get 208.
Take the next digit (3) from the dividend and append it to 208, then repeat: 2083 / 409

Let's proceed to step 6:
409 goes into 2083 5 times with a remainder of 38.
The next digit of our result is 5. 
Result so far: 2405.0
Subtracting 2045 from 2083 leaves us with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 409

Step 7:
If we divide 384 by 409, we get 0 and a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 24050.0
Deduct 0 from 384 and we're left with 384.
Append the next digit (9) from the dividend to 384 and continue with: 3849 / 409

Advancing to step 8:
409 can be fit into 3849 9 times, resulting in a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 240509.0
The remainder is 168 after subtracting 3681 from 3849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
If we divide 1680 by 409, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 240509.4
Subtract 1636 from 1680 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
440 divided by 409 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 240509.41
If we subtract 409 from 440, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
If we divide 310 by 409, we get 0 and a remainder of 310.
The next digit of our result is 0. 
Result so far: 240509.41
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
The number 409 fits into 3100 7 times, leaving a remainder of 237.
The next digit of our result is 7. 
Result so far: 240509.4107
Deduct 2863 from 3100 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 13:
The number 409 fits into 2370 5 times, leaving a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 240509.41075
The remainder is 325 after subtracting 2045 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 14:
3250 divided by 409 is 7 with a remainder of 387.
Put 7 as the next digit of the answer. 
Result so far: 240509.410757
Subtract 2863 from 3250 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Going ahead to step 15:
409 goes into 3870 9 times with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 240509.4107579
The remainder is 189 after subtracting 3681 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 16:
If we divide 1890 by 409, we get 4 and a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 240509.41075794
If we subtract 1636 from 1890, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

In conclusion, the division gives 240509.41075794 with a balance of 2.54e-07.
