638474 divided by 23 
Let's see how many times 23 fits into 638474.

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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 23

Let's proceed to step 2:
23 goes into 63 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 46 from 63 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 23

Going ahead to step 3:
The number 23 fits into 178 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 161 away from 178, we end up with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 23

Advancing to step 4:
If we divide 174 by 23, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 277.0
Subtracting 161 from 174 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 23

Advancing to step 5:
23 can be fit into 137 5 times, resulting in a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 2775.0
Subtract 115 from 137 to get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 23

On to step 6:
The number 23 fits into 224 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 27759.0
Subtract 207 from 224 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 23 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 27759.7
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
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: 27759.73
If we take 69 away from 90, we end up 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 9:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 27759.739
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.

Going ahead to step 10:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 27759.7391
Deduct 23 from 30 and we're left 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.

Step 11:
If we divide 70 by 23, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 27759.73913
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.

Let's proceed to step 12:
If we divide 10 by 23, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 27759.73913
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.

Advancing to step 13:
100 divided by 23 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 27759.7391304
Deduct 92 from 100 and we're left with 8.
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 14:
80 divided by 23 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 27759.73913043
Subtracting 69 from 80 leaves us 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.

Our division results in 27759.73913043 with a remaining 1.1e-08.
