Let's divide 66784590 by 450
Our goal is to divide 66784590 by 450.

Let's proceed to step 1:
450 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 450

On to step 2:
If we divide 66 by 450, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 450

On to step 3:
450 goes into 667 1 times with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 450 from 667 to get 217.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 450

Step 4:
If we divide 2178 by 450, we get 4 and a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1800 from 2178 leaves us with 378.
Include the next digit (4) from the dividend after 378, then repeat: 3784 / 450

Moving on to step 5:
450 goes into 3784 8 times with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Subtract 3600 from 3784 to get 184.
Fetch the next digit (5) from the dividend, attach it to 184 and continue: 1845 / 450

Going ahead to step 6:
When dividing 1845 by 450, we get 4 with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 1484.0
Subtracting 1800 from 1845 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 450

Step 7:
459 divided by 450 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 14841.0
Deduct 450 from 459 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 450

Moving on to step 8:
When dividing 90 by 450, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 148410.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
450 goes into 900 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 148410.2
Subtract 900 from 900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
450 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 148410.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
450 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 148410.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 148410.2, with a leftover of 0.0.
