We're dividing 638774 by 23 
We want to figure out the number of times 638774 can be divided by 23.

On to step 1:
6 divided by 23 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 23

Moving on to step 2:
If we divide 63 by 23, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 46 away from 63, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 23

Going ahead to step 3:
The number 23 fits into 178 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 161 from 178 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 23

Let's proceed to step 4:
The number 23 fits into 177 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 277.0
Subtracting 161 from 177 leaves us with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 23

Going ahead to step 5:
23 goes into 167 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 2777.0
If we subtract 161 from 167, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 23

On to step 6:
When dividing 64 by 23, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 27772.0
The remainder is 18 after subtracting 46 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 27772.7
If we take 161 away from 180, we end up 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.

Advancing to step 8:
When dividing 190 by 23, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 27772.78
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.

Moving on to step 9:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 27772.782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 27772.7826
Deduct 138 from 140 and we're left 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.

Moving on to step 11:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 27772.7826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 27772.782608
Subtracting 184 from 200 leaves us 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 13:
160 divided by 23 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 27772.7826086
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.

Moving on to step 14:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 27772.78260869
If we take 207 away from 220, we end up 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 final result is 27772.78260869 with a remainder of 1.3e-08.
