Going ahead to step 1:
8 divided by 23 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 23

Advancing to step 2:
89 divided by 23 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 69 from 89, we get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 23

Let's proceed to step 3:
When dividing 203 by 23, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 19 after subtracting 184 from 203.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 23

Step 4:
When dividing 195 by 23, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 388.0
If we subtract 184 from 195, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 23

Moving on to step 5:
23 can be fit into 114 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 3884.0
Subtract 92 from 114 to get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 23

Let's proceed to step 6:
When dividing 224 by 23, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 38849.0
The remainder is 17 after subtracting 207 from 224.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 23

Let's proceed to step 7:
23 can be fit into 173 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 388497.0
Deduct 161 from 173 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 23

Advancing to step 8:
23 can be fit into 121 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 3884975.0
Deduct 115 from 121 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 3884975.2
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 23, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 3884975.26
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
20 divided by 23 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3884975.26
Deduct 0 from 20 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.

Going ahead to step 12:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 3884975.2608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 23, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 3884975.26086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
23 goes into 220 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 3884975.260869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 15:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3884975.2608695
Subtracting 115 from 130 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.

Advancing to step 16:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 3884975.26086956
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 3884975.26086956 with a balance of 1.2e-08.
