We look at the division of 98428463 by 584 
The aim is to understand the frequency of 584 in 98428463.

Going ahead to step 1:
When dividing 9 by 584, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 584

Going ahead to step 2:
584 can be fit into 98 0 times, resulting in a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Fetch the next digit (4) from the dividend, attach it to 98 and continue: 984 / 584

Let's proceed to step 3:
584 can be fit into 984 1 times, resulting in a remainder of 400.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 584 from 984 to get 400.
Fetch the next digit (2) from the dividend, attach it to 400 and continue: 4002 / 584

On to step 4:
When dividing 4002 by 584, we get 6 with a remainder of 498.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 3504 from 4002, we get 498.
Fetch the next digit (8) from the dividend, attach it to 498 and continue: 4988 / 584

Going ahead to step 5:
584 goes into 4988 8 times with a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
If we take 4672 away from 4988, we end up with 316.
Fetch the next digit (4) from the dividend, attach it to 316 and continue: 3164 / 584

Advancing to step 6:
584 goes into 3164 5 times with a remainder of 244.
The next digit of our result is 5. 
Result so far: 1685.0
Subtract 2920 from 3164 to get 244.
Grab the next digit (6) from the dividend, add it to 244, then carry on: 2446 / 584

Moving on to step 7:
584 goes into 2446 4 times with a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 16854.0
Subtract 2336 from 2446 to get 110.
Include the next digit (3) from the dividend after 110, then repeat: 1103 / 584

Moving on to step 8:
When dividing 1103 by 584, we get 1 with a remainder of 519.
The number 1 becomes the next digit in our result. 
Result so far: 168541.0
If we subtract 584 from 1103, we get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 9:
The number 584 fits into 5190 8 times, leaving a remainder of 518.
Write down 8 as next digit of the result. 
Result so far: 168541.8
Subtracting 4672 from 5190 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
5180 divided by 584 is 8 with a remainder of 508.
Put 8 as the next digit of the answer. 
Result so far: 168541.88
If we subtract 4672 from 5180, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The final outcome is 168541.88, with a leftover of 0.508.
