638231 ÷ 48 
Let's see how many times 48 fits into 638231.

On to step 1:
6 divided by 48 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 48

Step 2:
The number 48 fits into 63 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 48 from 63 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 48

Step 3:
48 can be fit into 158 3 times, resulting in a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 144 from 158 leaves us with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 48

Let's proceed to step 4:
142 divided by 48 is 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Deduct 96 from 142 and we're left with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 48

Advancing to step 5:
463 divided by 48 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1329.0
Subtracting 432 from 463 leaves us with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 48

Moving on to step 6:
48 can be fit into 311 6 times, resulting in a remainder of 23.
The next digit of our result is 6. 
Result so far: 13296.0
Subtracting 288 from 311 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 48, we get 4 and a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 13296.4
The remainder is 38 after subtracting 192 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
When dividing 380 by 48, we get 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 13296.47
If we take 336 away from 380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
48 goes into 440 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 13296.479
If we take 432 away from 440, we end up 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 10:
80 divided by 48 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 13296.4791
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 13296.47916
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 13296.479166
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 13296.479166 with a remaining 3.2e-06.
