3898 divided by 8 
Our goal is to divide 3898 by 8.

On to step 1:
8 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Let's proceed to step 2:
The number 8 fits into 38 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 32 from 38 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 8

Let's proceed to step 3:
8 goes into 69 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 64 from 69 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 8

Going ahead to step 4:
When dividing 58 by 8, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 487.0
Subtracting 56 from 58 leaves us 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.

Step 5:
8 goes into 20 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 487.2
Deduct 16 from 20 and we're left 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 6:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 487.25
Subtracting 40 from 40 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.

On to step 7:
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: 487.25
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.

Moving on to step 8:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 487.25
If we take 0 away from 0, we end up 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.

After the division, we end up with 487.25 and a remainder of 0.0.
