We're dividing 98091821 by 512 
The aim is to understand the frequency of 512 in 98091821.

Moving on to step 1:
When dividing 9 by 512, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 512

Moving on to step 2:
98 divided by 512 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Include the next digit (0) from the dividend after 98, then repeat: 980 / 512

Moving on to step 3:
If we divide 980 by 512, we get 1 and a remainder of 468.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 512 from 980 to get 468.
Bring next digit (9) of the dividend behind the 468 and repeat the process: 4689 / 512

Going ahead to step 4:
When dividing 4689 by 512, we get 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 4608 from 4689 leaves us with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 512

Step 5:
When dividing 811 by 512, we get 1 with a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 191.0
Deduct 512 from 811 and we're left with 299.
Grab the next digit (8) from the dividend, add it to 299, then carry on: 2998 / 512

Going ahead to step 6:
The number 512 fits into 2998 5 times, leaving a remainder of 438.
Write down 5 as next digit of the result. 
Result so far: 1915.0
The remainder is 438 after subtracting 2560 from 2998.
Bring next digit (2) of the dividend behind the 438 and repeat the process: 4382 / 512

Advancing to step 7:
512 goes into 4382 8 times with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 19158.0
If we take 4096 away from 4382, we end up with 286.
Bring next digit (1) of the dividend behind the 286 and repeat the process: 2861 / 512

Advancing to step 8:
2861 divided by 512 is 5 with a remainder of 301.
Write down 5 as next digit of the result. 
Result so far: 191585.0
Subtracting 2560 from 2861 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
When dividing 3010 by 512, we get 5 with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 191585.5
Deduct 2560 from 3010 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
The number 512 fits into 4500 8 times, leaving a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 191585.58
Subtracting 4096 from 4500 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
If we divide 4040 by 512, we get 7 and a remainder of 456.
The next digit of our result is 7. 
Result so far: 191585.587
If we subtract 3584 from 4040, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 12:
4560 divided by 512 is 8 with a remainder of 464.
Write down 8 as next digit of the result. 
Result so far: 191585.5878
If we subtract 4096 from 4560, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
512 can be fit into 4640 9 times, resulting in a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 191585.58789
Subtract 4608 from 4640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
512 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 191585.58789
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
If we divide 3200 by 512, we get 6 and a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 191585.5878906
Subtract 3072 from 3200 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
If we divide 1280 by 512, we get 2 and a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 191585.58789062
Subtracting 1024 from 1280 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 191585.58789062 with a remaining 2.56e-07.
