Let's divide 77178305 by 450
We want to divide 77178305 by 450.

Moving on to step 1:
450 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 450

Going ahead to step 2:
When dividing 77 by 450, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 450

Moving on to step 3:
771 divided by 450 is 1 with a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 450 from 771 and we're left with 321.
Include the next digit (7) from the dividend after 321, then repeat: 3217 / 450

Step 4:
The number 450 fits into 3217 7 times, leaving a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 3150 away from 3217, we end up with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 450

Going ahead to step 5:
If we divide 678 by 450, we get 1 and a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtracting 450 from 678 leaves us with 228.
Include the next digit (3) from the dividend after 228, then repeat: 2283 / 450

On to step 6:
When dividing 2283 by 450, we get 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 1715.0
Deduct 2250 from 2283 and we're left with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 450

Let's proceed to step 7:
450 goes into 330 0 times with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 17150.0
The remainder is 330 after subtracting 0 from 330.
Bring next digit (5) of the dividend behind the 330 and repeat the process: 3305 / 450

On to step 8:
If we divide 3305 by 450, we get 7 and a remainder of 155.
The number 7 becomes the next digit in our result. 
Result so far: 171507.0
If we subtract 3150 from 3305, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
450 can be fit into 1550 3 times, resulting in a remainder of 200.
The number 3 becomes the next digit in our result. 
Result so far: 171507.3
Deduct 1350 from 1550 and we're left 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.
Record the quotient 4 as the next digit in the result. 
Result so far: 171507.34
Subtract 1800 from 2000 to 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.

Step 11:
450 can be fit into 2000 4 times, resulting in a remainder of 200.
The next digit of our result is 4. 
Result so far: 171507.344
Subtract 1800 from 2000 to 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.

Our division results in 171507.344 with a remaining 0.02.
