866125 ÷ 23 
We're looking to find how many times 23 goes into 866125.

Moving on to step 1:
23 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 23

Moving on to step 2:
When dividing 86 by 23, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 69 from 86 and we're left with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 23

Advancing to step 3:
23 can be fit into 176 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 161 from 176 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 23

Advancing to step 4:
The number 23 fits into 151 6 times, leaving a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
Subtract 138 from 151 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 23

Step 5:
When dividing 132 by 23, we get 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 3765.0
If we subtract 115 from 132, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 23

Moving on to step 6:
23 goes into 175 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 37657.0
Subtracting 161 from 175 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.

Step 7:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 37657.6
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 37657.6
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
23 goes into 200 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 37657.608
If we subtract 184 from 200, we 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 10:
160 divided by 23 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 37657.6086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 37657.60869
If we take 207 away from 220, we end up 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.

On to step 12:
130 divided by 23 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 37657.608695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 23 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 37657.6086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37657.60869565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 37657.60869565 with a remainder of 5e-09.
