878778 ÷ 23 
Our goal is to divide 878778 by 23.

Step 1:
23 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 23

On to step 2:
23 goes into 87 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 18 after subtracting 69 from 87.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 23

On to step 3:
23 goes into 188 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 184 away from 188, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 23

Advancing to step 4:
23 goes into 47 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 382.0
If we take 46 away from 47, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 23

Step 5:
23 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 3820.0
If we subtract 0 from 17, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 23

Going ahead to step 6:
If we divide 178 by 23, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 38207.0
Subtract 161 from 178 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 38207.7
Deduct 161 from 170 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 23, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 38207.73
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 23, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 38207.739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 38207.7391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 38207.73913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
10 divided by 23 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 38207.73913
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 38207.7391304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
80 divided by 23 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 38207.73913043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 38207.73913043, with a leftover of 1.1e-08.
