20867403 ÷ 450 
Let's see how many times 450 fits into 20867403.

Step 1:
The number 450 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 450

Moving on to step 2:
450 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 450

On to step 3:
208 divided by 450 is 0 with a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Take the next digit (6) from the dividend and append it to 208, then repeat: 2086 / 450

Step 4:
When dividing 2086 by 450, we get 4 with a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1800 away from 2086, we end up with 286.
Take the next digit (7) from the dividend and append it to 286, then repeat: 2867 / 450

Advancing to step 5:
When dividing 2867 by 450, we get 6 with a remainder of 167.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 2700 from 2867 and we're left with 167.
Take the next digit (4) from the dividend and append it to 167, then repeat: 1674 / 450

Advancing to step 6:
The number 450 fits into 1674 3 times, leaving a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
If we subtract 1350 from 1674, we get 324.
Grab the next digit (0) from the dividend, add it to 324, then carry on: 3240 / 450

Moving on to step 7:
3240 divided by 450 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 4637.0
Subtract 3150 from 3240 to get 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 450

Moving on to step 8:
450 goes into 903 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 46372.0
Subtracting 900 from 903 leaves us 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.

Advancing to step 9:
When dividing 30 by 450, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 46372.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
450 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 46372.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 46372.0 with a remaining 0.3.
