8678144 divided by 450 
We want to divide 8678144 by 450.

Moving on to step 1:
8 divided by 450 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 450

On to step 2:
450 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 450

Going ahead to step 3:
When dividing 867 by 450, we get 1 with a remainder of 417.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 417 after subtracting 450 from 867.
Grab the next digit (8) from the dividend, add it to 417, then carry on: 4178 / 450

Going ahead to step 4:
When dividing 4178 by 450, we get 9 with a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 4050 from 4178 leaves us with 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 450

Advancing to step 5:
450 can be fit into 1281 2 times, resulting in a remainder of 381.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Deduct 900 from 1281 and we're left with 381.
Take the next digit (4) from the dividend and append it to 381, then repeat: 3814 / 450

Step 6:
If we divide 3814 by 450, we get 8 and a remainder of 214.
The next digit of our result is 8. 
Result so far: 1928.0
If we subtract 3600 from 3814, we get 214.
Fetch the next digit (4) from the dividend, attach it to 214 and continue: 2144 / 450

On to step 7:
When dividing 2144 by 450, we get 4 with a remainder of 344.
Write down 4 as next digit of the result. 
Result so far: 19284.0
The remainder is 344 after subtracting 1800 from 2144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 8:
450 can be fit into 3440 7 times, resulting in a remainder of 290.
Use 7 as the next digit of our solution. 
Result so far: 19284.7
Subtracting 3150 from 3440 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
2900 divided by 450 is 6 with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 19284.76
Subtracting 2700 from 2900 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
450 can be fit into 2000 4 times, resulting in a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 19284.764
If we take 1800 away from 2000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
If we divide 2000 by 450, we get 4 and a remainder of 200.
The number 4 becomes the next digit in our result. 
Result so far: 19284.7644
If we subtract 1800 from 2000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 19284.7644 and a remainder of 0.002.
