We're dividing 428955 by 12 
We want to divide 428955 by 12.

On to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Step 2:
12 can be fit into 42 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 36 from 42 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Going ahead to step 3:
When dividing 68 by 12, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 60 away from 68, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Advancing to step 4:
89 divided by 12 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
Subtract 84 from 89 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 12

Step 5:
If we divide 55 by 12, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 3574.0
Subtracting 48 from 55 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 12

Going ahead to step 6:
If we divide 75 by 12, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 35746.0
If we take 72 away from 75, we end up with 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:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 35746.2
If we subtract 24 from 30, we 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.

Advancing to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35746.25
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.

Going ahead to step 9:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35746.25
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:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35746.25
Subtract 0 from 0 to 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.

After the division, we end up with 35746.25 and a remainder of 0.0.
