80588254 ÷ 450 
Let's see how many times 450 fits into 80588254.

Advancing to step 1:
The number 450 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 450

Advancing to step 2:
450 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 450

Let's proceed to step 3:
The number 450 fits into 805 1 times, leaving a remainder of 355.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 450 from 805 to get 355.
Grab the next digit (8) from the dividend, add it to 355, then carry on: 3558 / 450

Step 4:
450 goes into 3558 7 times with a remainder of 408.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3150 from 3558 leaves us with 408.
Take the next digit (8) from the dividend and append it to 408, then repeat: 4088 / 450

Advancing to step 5:
When dividing 4088 by 450, we get 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 179.0
If we subtract 4050 from 4088, we get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 450

Let's proceed to step 6:
The number 450 fits into 382 0 times, leaving a remainder of 382.
Write down 0 as next digit of the result. 
Result so far: 1790.0
Subtracting 0 from 382 leaves us with 382.
Take the next digit (5) from the dividend and append it to 382, then repeat: 3825 / 450

Moving on to step 7:
450 goes into 3825 8 times with a remainder of 225.
Put 8 as the next digit of the answer. 
Result so far: 17908.0
Subtract 3600 from 3825 to get 225.
Include the next digit (4) from the dividend after 225, then repeat: 2254 / 450

Moving on to step 8:
If we divide 2254 by 450, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 179085.0
Deduct 2250 from 2254 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 450, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 179085.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 450, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 179085.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 179085.0 with a remaining 0.4.
