385759 ÷ 12 
We want to figure out the number of times 385759 can be divided by 12.

Advancing to step 1:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

Advancing to step 2:
38 divided by 12 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 36 from 38 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Moving on to step 3:
When dividing 25 by 12, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

On to step 4:
12 goes into 17 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 321.0
Deduct 12 from 17 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 12

Advancing to step 5:
12 goes into 55 4 times with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 3214.0
Subtracting 48 from 55 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

Step 6:
12 goes into 79 6 times with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 32146.0
Deduct 72 from 79 and we're left 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.

Let's proceed to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 32146.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 32146.58
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.

Let's proceed to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 32146.583
Deduct 36 from 40 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.

Moving on to step 10:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 32146.5833
Deduct 36 from 40 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.

The final result is 32146.5833 with a remainder of 4e-05.
