We look at the division of 88889231 by 585 
The aim is to understand the frequency of 585 in 88889231.

Going ahead to step 1:
The number 585 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 585

Step 2:
If we divide 88 by 585, we get 0 and a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 585

Step 3:
888 divided by 585 is 1 with a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 585 from 888 and we're left with 303.
Include the next digit (8) from the dividend after 303, then repeat: 3038 / 585

Going ahead to step 4:
585 goes into 3038 5 times with a remainder of 113.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2925 from 3038 leaves us with 113.
Bring next digit (9) of the dividend behind the 113 and repeat the process: 1139 / 585

Step 5:
The number 585 fits into 1139 1 times, leaving a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we subtract 585 from 1139, we get 554.
Grab the next digit (2) from the dividend, add it to 554, then carry on: 5542 / 585

Going ahead to step 6:
5542 divided by 585 is 9 with a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 1519.0
Subtracting 5265 from 5542 leaves us with 277.
Append the next digit (3) from the dividend to 277 and continue with: 2773 / 585

Going ahead to step 7:
When dividing 2773 by 585, we get 4 with a remainder of 433.
Use 4 as the next digit of our solution. 
Result so far: 15194.0
Deduct 2340 from 2773 and we're left with 433.
Bring next digit (1) of the dividend behind the 433 and repeat the process: 4331 / 585

Moving on to step 8:
The number 585 fits into 4331 7 times, leaving a remainder of 236.
Use 7 as the next digit of our solution. 
Result so far: 151947.0
The remainder is 236 after subtracting 4095 from 4331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 9:
585 can be fit into 2360 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 151947.4
If we subtract 2340 from 2360, 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.

Step 10:
585 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 151947.4
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
2000 divided by 585 is 3 with a remainder of 245.
The number 3 becomes the next digit in our result. 
Result so far: 151947.403
Deduct 1755 from 2000 and we're left 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.

Moving on to step 12:
2450 divided by 585 is 4 with a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 151947.4034
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.

Let's proceed to step 13:
When dividing 1100 by 585, we get 1 with a remainder of 515.
Write down 1 as next digit of the result. 
Result so far: 151947.40341
Deduct 585 from 1100 and we're left 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.

Moving on to step 14:
If we divide 5150 by 585, we get 8 and a remainder of 470.
Record the quotient 8 as the next digit in the result. 
Result so far: 151947.403418
Subtract 4680 from 5150 to 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.

On to step 15:
The number 585 fits into 4700 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 151947.4034188
Deduct 4680 from 4700 and we're left with 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 outcome is 151947.4034188, with a leftover of 2e-07.
