The aim is to understand the frequency of 285 in 88021451.

Advancing to step 1:
8 divided by 285 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 285

On to step 2:
285 goes into 88 0 times with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 285

Step 3:
The number 285 fits into 880 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 855 from 880 to get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 285

Step 4:
When dividing 252 by 285, we get 0 with a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 252 to get 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 285

Let's proceed to step 5:
If we divide 2521 by 285, we get 8 and a remainder of 241.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
Subtracting 2280 from 2521 leaves us with 241.
Take the next digit (4) from the dividend and append it to 241, then repeat: 2414 / 285

Going ahead to step 6:
If we divide 2414 by 285, we get 8 and a remainder of 134.
Use 8 as the next digit of our solution. 
Result so far: 3088.0
Deduct 2280 from 2414 and we're left with 134.
Take the next digit (5) from the dividend and append it to 134, then repeat: 1345 / 285

Step 7:
285 can be fit into 1345 4 times, resulting in a remainder of 205.
Write down 4 as next digit of the result. 
Result so far: 30884.0
If we subtract 1140 from 1345, we get 205.
Bring next digit (1) of the dividend behind the 205 and repeat the process: 2051 / 285

Advancing to step 8:
285 goes into 2051 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 308847.0
Subtract 1995 from 2051 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
285 can be fit into 560 1 times, resulting in a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 308847.1
The remainder is 275 after subtracting 285 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 10:
285 goes into 2750 9 times with a remainder of 185.
The number 9 becomes the next digit in our result. 
Result so far: 308847.19
Deduct 2565 from 2750 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 11:
1850 divided by 285 is 6 with a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 308847.196
The remainder is 140 after subtracting 1710 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
If we divide 1400 by 285, we get 4 and a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 308847.1964
If we subtract 1140 from 1400, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
2600 divided by 285 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 308847.19649
The remainder is 35 after subtracting 2565 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
285 can be fit into 350 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 308847.196491
The remainder is 65 after subtracting 285 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 15:
If we divide 650 by 285, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 308847.1964912
Subtract 570 from 650 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
When dividing 800 by 285, we get 2 with a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 308847.19649122
The remainder is 230 after subtracting 570 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

In conclusion, the division gives 308847.19649122 with a balance of 2.3e-07.
