97998513 ÷ 459 
The aim is to understand the frequency of 459 in 97998513.

Step 1:
9 divided by 459 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 459

Moving on to step 2:
When dividing 97 by 459, we get 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Take the next digit (9) from the dividend and append it to 97, then repeat: 979 / 459

Let's proceed to step 3:
459 goes into 979 2 times with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 918 from 979 leaves us with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 459

Step 4:
459 goes into 619 1 times with a remainder of 160.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 459 from 619 and we're left with 160.
Include the next digit (8) from the dividend after 160, then repeat: 1608 / 459

Moving on to step 5:
459 goes into 1608 3 times with a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
If we take 1377 away from 1608, we end up with 231.
Bring next digit (5) of the dividend behind the 231 and repeat the process: 2315 / 459

Step 6:
2315 divided by 459 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2135.0
Deduct 2295 from 2315 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 459

Going ahead to step 7:
201 divided by 459 is 0 with a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 21350.0
If we take 0 away from 201, we end up with 201.
Append the next digit (3) from the dividend to 201 and continue with: 2013 / 459

Moving on to step 8:
The number 459 fits into 2013 4 times, leaving a remainder of 177.
The next digit of our result is 4. 
Result so far: 213504.0
If we subtract 1836 from 2013, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 9:
459 goes into 1770 3 times with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 213504.3
If we subtract 1377 from 1770, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 10:
If we divide 3930 by 459, we get 8 and a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 213504.38
If we take 3672 away from 3930, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 11:
The number 459 fits into 2580 5 times, leaving a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 213504.385
Deduct 2295 from 2580 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 12:
459 goes into 2850 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 213504.3856
Deduct 2754 from 2850 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
When dividing 960 by 459, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 213504.38562
If we take 918 away from 960, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
420 divided by 459 is 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 213504.38562
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
If we divide 4200 by 459, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 213504.3856209
If we take 4131 away from 4200, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 16:
When dividing 690 by 459, we get 1 with a remainder of 231.
The next digit of our result is 1. 
Result so far: 213504.38562091
Subtracting 459 from 690 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Our division results in 213504.38562091 with a remaining 2.31e-07.
