621877 divided by 23 
Let's see how many times 23 fits into 621877.

Step 1:
23 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 23

Going ahead to step 2:
The number 23 fits into 62 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 46 from 62 leaves us with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 23

Going ahead to step 3:
23 goes into 161 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 161 away from 161, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 23

On to step 4:
23 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 270.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 23

Let's proceed to step 5:
23 goes into 87 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 2703.0
If we take 69 away from 87, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 23

Step 6:
187 divided by 23 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 27038.0
Deduct 184 from 187 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 27038.1
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.

On to step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 27038.13
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 27038.13
Deduct 0 from 10 and we're left 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.

Let's proceed to step 10:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 27038.1304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 23, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 27038.13043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 27038.130434
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.

Moving on to step 13:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 27038.1304347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
If we divide 190 by 23, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 27038.13043478
If we subtract 184 from 190, we 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.

Our division results in 27038.13043478 with a remaining 6e-09.
