1379073 ÷ 450 
Let's see how many times 450 fits into 1379073.

Going ahead to step 1:
The number 450 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 450

Step 2:
The number 450 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 450

Going ahead to step 3:
137 divided by 450 is 0 with a remainder of 137.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 137, we get 137.
Take the next digit (9) from the dividend and append it to 137, then repeat: 1379 / 450

Going ahead to step 4:
When dividing 1379 by 450, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1350 away from 1379, we end up with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 450

Advancing to step 5:
If we divide 290 by 450, we get 0 and a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 290 and we're left with 290.
Bring next digit (7) of the dividend behind the 290 and repeat the process: 2907 / 450

Let's proceed to step 6:
2907 divided by 450 is 6 with a remainder of 207.
Use 6 as the next digit of our solution. 
Result so far: 306.0
If we subtract 2700 from 2907, we get 207.
Append the next digit (3) from the dividend to 207 and continue with: 2073 / 450

Moving on to step 7:
If we divide 2073 by 450, we get 4 and a remainder of 273.
Write down 4 as next digit of the result. 
Result so far: 3064.0
Subtracting 1800 from 2073 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 8:
When dividing 2730 by 450, we get 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 3064.6
If we take 2700 away from 2730, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
450 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 3064.6
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
If we divide 3000 by 450, we get 6 and a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 3064.606
If we subtract 2700 from 3000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
450 can be fit into 3000 6 times, resulting in a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 3064.6066
Subtract 2700 from 3000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 3064.6066 with a remainder of 0.003.
