621685 ÷ 23 
Let's see how many times 23 fits into 621685.

Let's proceed to step 1:
23 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 23

Let's proceed to step 2:
23 can be fit into 62 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 46 from 62 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 23

On to step 3:
The number 23 fits into 161 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 161 from 161 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 23

Let's proceed to step 4:
If we divide 6 by 23, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 270.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 23

Moving on to step 5:
If we divide 68 by 23, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 2702.0
The remainder is 22 after subtracting 46 from 68.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 23

Step 6:
When dividing 225 by 23, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 27029.0
Subtract 207 from 225 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 27029.7
Subtracting 161 from 180 leaves us 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.

Moving on to step 8:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 27029.78
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.

Going ahead to step 9:
60 divided by 23 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 27029.782
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.

Going ahead to step 10:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 27029.7826
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 11:
When dividing 20 by 23, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 27029.7826
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.

Moving on to step 12:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 27029.782608
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.

Going ahead to step 13:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 27029.7826086
If we take 138 away from 160, we end up 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.

On to step 14:
23 can be fit into 220 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 27029.78260869
Subtracting 207 from 220 leaves us 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.

The quotient of the division is 27029.78260869, and the remainder is 1.3e-08.
