428779 divided by 12 
We want to divide 428779 by 12.

Step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Moving on to step 2:
12 can be fit into 42 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 36 from 42 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Advancing to step 3:
If we divide 68 by 12, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 8 after subtracting 60 from 68.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

Advancing to step 4:
If we divide 87 by 12, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 357.0
Deduct 84 from 87 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Step 5:
The number 12 fits into 37 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3573.0
Deduct 36 from 37 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Going ahead to step 6:
The number 12 fits into 19 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 35731.0
The remainder is 7 after subtracting 12 from 19.
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:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 35731.5
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.

Advancing to step 8:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 35731.58
If we subtract 96 from 100, 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.

Moving on to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 35731.583
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.

Going ahead to step 10:
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: 35731.5833
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.

After the division, we end up with 35731.5833 and a remainder of 4e-05.
