878911 ÷ 23 
Our goal is to divide 878911 by 23.

Going ahead to step 1:
23 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 23

Going ahead to step 2:
23 goes into 87 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 69 from 87 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 23

Let's proceed to step 3:
If we divide 188 by 23, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 184 from 188 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

On to step 4:
When dividing 49 by 23, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 382.0
The remainder is 3 after subtracting 46 from 49.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 23

Step 5:
If we divide 31 by 23, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 3821.0
If we take 23 away from 31, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 23

Going ahead to step 6:
23 can be fit into 81 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 38213.0
Deduct 69 from 81 and we're left 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.

Going ahead to step 7:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 38213.5
If we subtract 115 from 120, we 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.

Going ahead to step 8:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 38213.52
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 23, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 38213.521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 23 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 38213.5217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 38213.52173
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.

On to step 12:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 38213.521739
The remainder is 3 after subtracting 207 from 210.
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 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 38213.5217391
Subtracting 23 from 30 leaves us 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.

Going ahead to step 14:
23 goes into 70 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 38213.52173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 38213.52173913 with a remainder of 1e-09.
