Let's divide 385915 by 12
We want to figure out the number of times 385915 can be divided by 12.

On to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Moving on to step 2:
The number 12 fits into 38 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 36 from 38 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Going ahead to step 3:
25 divided by 12 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 24 away from 25, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Moving on to step 4:
If we divide 19 by 12, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
Subtract 12 from 19 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

On to step 5:
If we divide 71 by 12, we get 5 and a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 3215.0
If we subtract 60 from 71, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 12

Let's proceed to step 6:
If we divide 115 by 12, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 32159.0
Subtracting 108 from 115 leaves us 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.

Step 7:
12 goes into 70 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 32159.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 32159.58
Deduct 96 from 100 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.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 32159.583
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 32159.5833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 32159.5833, with a leftover of 4e-05.
