We look at the division of 9587584 by 585 
The aim is to understand the frequency of 585 in 9587584.

Going ahead to step 1:
585 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 585

Let's proceed to step 2:
585 can be fit into 95 0 times, resulting in a remainder of 95.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 95 after subtracting 0 from 95.
Grab the next digit (8) from the dividend, add it to 95, then carry on: 958 / 585

Going ahead to step 3:
585 goes into 958 1 times with a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 585 from 958 leaves us with 373.
Append the next digit (7) from the dividend to 373 and continue with: 3737 / 585

Advancing to step 4:
The number 585 fits into 3737 6 times, leaving a remainder of 227.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 227 after subtracting 3510 from 3737.
Include the next digit (5) from the dividend after 227, then repeat: 2275 / 585

On to step 5:
The number 585 fits into 2275 3 times, leaving a remainder of 520.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we subtract 1755 from 2275, we get 520.
Take the next digit (8) from the dividend and append it to 520, then repeat: 5208 / 585

On to step 6:
5208 divided by 585 is 8 with a remainder of 528.
Record the quotient 8 as the next digit in the result. 
Result so far: 1638.0
Subtracting 4680 from 5208 leaves us with 528.
Include the next digit (4) from the dividend after 528, then repeat: 5284 / 585

Going ahead to step 7:
If we divide 5284 by 585, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 16389.0
If we subtract 5265 from 5284, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
585 goes into 190 0 times with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 16389.0
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 9:
When dividing 1900 by 585, we get 3 with a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 16389.03
Subtract 1755 from 1900 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 10:
585 goes into 1450 2 times with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 16389.032
Subtracting 1170 from 1450 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
If we divide 2800 by 585, we get 4 and a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 16389.0324
The remainder is 460 after subtracting 2340 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 12:
If we divide 4600 by 585, we get 7 and a remainder of 505.
Use 7 as the next digit of our solution. 
Result so far: 16389.03247
If we take 4095 away from 4600, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 13:
If we divide 5050 by 585, we get 8 and a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 16389.032478
Subtracting 4680 from 5050 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 14:
3700 divided by 585 is 6 with a remainder of 190.
The next digit of our result is 6. 
Result so far: 16389.0324786
If we subtract 3510 from 3700, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
585 goes into 1900 3 times with a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 16389.03247863
Subtract 1755 from 1900 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 16389.03247863 with a remaining 1.45e-07.
