We look at the division of 450769 by 12 
We want to divide 450769 by 12.

Step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 12

On to step 2:
12 goes into 45 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 36 from 45 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

Moving on to step 3:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 84 from 90 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 12

Advancing to step 4:
67 divided by 12 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 375.0
Subtract 60 from 67 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 12

Step 5:
76 divided by 12 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3756.0
The remainder is 4 after subtracting 72 from 76.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 12

Advancing to step 6:
49 divided by 12 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 37564.0
Deduct 48 from 49 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 37564.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 37564.08
If we take 96 away from 100, 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.

On to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 37564.083
Subtracting 36 from 40 leaves us 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.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 37564.0833
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 37564.0833 and a remainder of 4e-05.
