Let's divide 388579 by 12
We want to figure out the number of times 388579 can be divided by 12.

On to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Let's proceed 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
The remainder is 2 after subtracting 36 from 38.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 12

On to step 3:
If we divide 28 by 12, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 24 from 28 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 12

Going ahead to step 4:
If we divide 45 by 12, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 323.0
Subtracting 36 from 45 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

On to step 5:
12 goes into 97 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 3238.0
Subtracting 96 from 97 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 12

Advancing to step 6:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 32381.0
Subtracting 12 from 19 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.

Moving on to step 7:
70 divided by 12 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 32381.5
Deduct 60 from 70 and we're left 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.

Step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 32381.58
Subtract 96 from 100 to 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.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 32381.583
Subtract 36 from 40 to 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.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 32381.5833
If we take 36 away from 40, 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.

After the division, we end up with 32381.5833 and a remainder of 4e-05.
