53668568 divided by 585 
The aim is to understand the frequency of 585 in 53668568.

Moving on to step 1:
When dividing 5 by 585, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 585

Going ahead to step 2:
585 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 585

Let's proceed to step 3:
585 can be fit into 536 0 times, resulting in a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 536 to get 536.
Take the next digit (6) from the dividend and append it to 536, then repeat: 5366 / 585

Step 4:
If we divide 5366 by 585, we get 9 and a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 5265 from 5366 to get 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 585

Let's proceed to step 5:
When dividing 1018 by 585, we get 1 with a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 585 from 1018 leaves us with 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 585

Going ahead to step 6:
The number 585 fits into 4335 7 times, leaving a remainder of 240.
The next digit of our result is 7. 
Result so far: 917.0
If we subtract 4095 from 4335, we get 240.
Append the next digit (6) from the dividend to 240 and continue with: 2406 / 585

On to step 7:
585 can be fit into 2406 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 9174.0
If we subtract 2340 from 2406, we get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 585

Advancing to step 8:
668 divided by 585 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 91741.0
Subtracting 585 from 668 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
585 goes into 830 1 times with a remainder of 245.
The next digit of our result is 1. 
Result so far: 91741.1
If we take 585 away from 830, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 10:
585 can be fit into 2450 4 times, resulting in a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 91741.14
Deduct 2340 from 2450 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
585 can be fit into 1100 1 times, resulting in a remainder of 515.
Write down 1 as next digit of the result. 
Result so far: 91741.141
If we take 585 away from 1100, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 12:
585 goes into 5150 8 times with a remainder of 470.
Put 8 as the next digit of the answer. 
Result so far: 91741.1418
If we subtract 4680 from 5150, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 13:
4700 divided by 585 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 91741.14188
If we subtract 4680 from 4700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 91741.14188 with a remainder of 2e-05.
