381919 divided by 12 
We're looking to find how many times 12 goes into 381919.

Advancing to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 12

On to step 2:
38 divided by 12 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 36 away from 38, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 12

Moving on to step 3:
12 can be fit into 21 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 12 from 21 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

On to step 4:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Subtract 96 from 99 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Step 5:
12 goes into 31 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 3182.0
Subtract 24 from 31 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

On to step 6:
12 can be fit into 79 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 31826.0
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.

Going ahead to step 7:
12 goes into 70 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 31826.5
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.

Going ahead to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 31826.58
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.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 31826.583
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.

On to step 10:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 31826.5833
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 quotient of the division is 31826.5833, and the remainder is 4e-05.
