388638 ÷ 8 
We want to divide 388638 by 8.

Moving on to step 1:
If we divide 3 by 8, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 8

Step 2:
38 divided by 8 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 32 from 38 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 8

Moving on to step 3:
If we divide 68 by 8, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 64 from 68 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 8

Let's proceed to step 4:
The number 8 fits into 46 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 485.0
Subtract 40 from 46 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 8

Step 5:
The number 8 fits into 63 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 4857.0
If we take 56 away from 63, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 8

Going ahead to step 6:
If we divide 78 by 8, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 48579.0
Subtract 72 from 78 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.

Step 7:
8 goes into 60 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 48579.7
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 8, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 48579.75
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48579.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 48579.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 48579.75 and a remainder of 0.0.
