Let's divide 638913 by 23
Let's see how many times 23 fits into 638913.

On to step 1:
23 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 23

Advancing to step 2:
If we divide 63 by 23, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 46 from 63, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 23

Going ahead to step 3:
23 can be fit into 178 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 161 away from 178, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 23

Step 4:
If we divide 179 by 23, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 277.0
Subtract 161 from 179 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 23

Advancing to step 5:
181 divided by 23 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 2777.0
Deduct 161 from 181 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 23

Step 6:
23 goes into 203 8 times with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 27778.0
Deduct 184 from 203 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.

Let's proceed to step 7:
23 goes into 190 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 27778.8
The remainder is 6 after subtracting 184 from 190.
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 8:
60 divided by 23 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 27778.82
If we subtract 46 from 60, we get 14.
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 9:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 27778.826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 23, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 27778.826
The remainder is 20 after subtracting 0 from 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 11:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 27778.82608
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 12:
160 divided by 23 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 27778.826086
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.

Moving on to step 13:
220 divided by 23 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 27778.8260869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
130 divided by 23 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 27778.82608695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 27778.82608695 with a remainder of 1.5e-08.
