38870 divided by 12 
We're looking to find how many times 12 goes into 38870.

Step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

Step 2:
When dividing 38 by 12, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 36 from 38 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Going ahead to step 3:
28 divided by 12 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 4 after subtracting 24 from 28.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 12

On to step 4:
When dividing 47 by 12, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 323.0
If we subtract 36 from 47, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 12

Moving on to step 5:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 3239.0
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 3239.1
Subtracting 12 from 20 leaves us 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.

Moving on to step 7:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3239.16
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 3239.166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3239.166, and the remainder is 0.0008.
