Let's divide 864144 by 23
We want to figure out the number of times 864144 can be divided by 23.

Advancing to step 1:
23 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 23

Let's proceed 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
If we subtract 69 from 86, we get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 23

Moving on to step 3:
23 goes into 174 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 161 away from 174, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 23

On to step 4:
When dividing 131 by 23, we get 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 375.0
If we subtract 115 from 131, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 23

Step 5:
164 divided by 23 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 3757.0
Deduct 161 from 164 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 23

Going ahead to step 6:
If we divide 34 by 23, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 37571.0
The remainder is 11 after subtracting 23 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 37571.4
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 37571.47
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
23 goes into 190 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 37571.478
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
When dividing 60 by 23, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 37571.4782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
23 goes into 140 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 37571.47826
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.

Moving on to step 12:
23 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 37571.47826
Subtracting 0 from 20 leaves us 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.

Step 13:
If we divide 200 by 23, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 37571.4782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
When dividing 160 by 23, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 37571.47826086
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.

The final result is 37571.47826086 with a remainder of 2.2e-08.
