783819 divided by 12 
We want to divide 783819 by 12.

Step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Moving on to step 2:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Moving on to step 3:
When dividing 63 by 12, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 60 from 63 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Moving on to step 4:
38 divided by 12 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 653.0
The remainder is 2 after subtracting 36 from 38.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Let's proceed to step 5:
If we divide 21 by 12, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 6531.0
Deduct 12 from 21 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Moving on to step 6:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 65318.0
Subtract 96 from 99 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 65318.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65318.25
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65318.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 65318.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 65318.25, with a leftover of 0.0.
