We look at the division of 387215 by 8 
We want to divide 387215 by 8.

Going ahead to step 1:
When dividing 3 by 8, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Moving on to step 2:
38 divided by 8 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 32 away from 38, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 8

Step 3:
8 can be fit into 67 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 3 after subtracting 64 from 67.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 8

Step 4:
When dividing 32 by 8, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtract 32 from 32 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 8

Let's proceed to step 5:
When dividing 1 by 8, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 4840.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 8

Going ahead to step 6:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 48401.0
If we take 8 away from 15, we end up 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.

Moving on to step 7:
8 goes into 70 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 48401.8
If we take 64 away from 70, we end up with 6.
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:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 48401.87
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 48401.875
If we subtract 40 from 40, we 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.

On to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48401.875
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.

Advancing to step 11:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48401.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 48401.875 with a remainder of 0.0.
