We're dividing 89866626 by 585 
The aim is to understand the frequency of 585 in 89866626.

Step 1:
When dividing 8 by 585, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 585

Moving on to step 2:
585 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 585

Advancing to step 3:
The number 585 fits into 898 1 times, leaving a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 585 away from 898, we end up with 313.
Take the next digit (6) from the dividend and append it to 313, then repeat: 3136 / 585

Going ahead to step 4:
When dividing 3136 by 585, we get 5 with a remainder of 211.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 211 after subtracting 2925 from 3136.
Take the next digit (6) from the dividend and append it to 211, then repeat: 2116 / 585

Moving on to step 5:
The number 585 fits into 2116 3 times, leaving a remainder of 361.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we subtract 1755 from 2116, we get 361.
Append the next digit (6) from the dividend to 361 and continue with: 3616 / 585

Step 6:
585 goes into 3616 6 times with a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 1536.0
Subtracting 3510 from 3616 leaves us with 106.
Bring next digit (2) of the dividend behind the 106 and repeat the process: 1062 / 585

Moving on to step 7:
1062 divided by 585 is 1 with a remainder of 477.
The number 1 becomes the next digit in our result. 
Result so far: 15361.0
Deduct 585 from 1062 and we're left with 477.
Grab the next digit (6) from the dividend, add it to 477, then carry on: 4776 / 585

On to step 8:
When dividing 4776 by 585, we get 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 153618.0
If we take 4680 away from 4776, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 585 fits into 960 1 times, leaving a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 153618.1
The remainder is 375 after subtracting 585 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 10:
585 goes into 3750 6 times with a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 153618.16
The remainder is 240 after subtracting 3510 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
When dividing 2400 by 585, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 153618.164
Subtract 2340 from 2400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
585 goes into 600 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 153618.1641
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
585 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 153618.1641
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
The number 585 fits into 1500 2 times, leaving a remainder of 330.
Use 2 as the next digit of our solution. 
Result so far: 153618.164102
Deduct 1170 from 1500 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 15:
585 goes into 3300 5 times with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 153618.1641025
Subtract 2925 from 3300 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 16:
3750 divided by 585 is 6 with a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 153618.16410256
Subtract 3510 from 3750 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 153618.16410256 with a remaining 2.4e-07.
