90047251 ÷ 450 
We're looking to find how many times 450 goes into 90047251.

Going ahead to step 1:
When dividing 9 by 450, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 450

Let's proceed to step 2:
The number 450 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 450

Step 3:
If we divide 900 by 450, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 900 away from 900, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 450

Going ahead to step 4:
450 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 450

Step 5:
If we divide 47 by 450, we get 0 and a remainder of 47.
The next digit of our result is 0. 
Result so far: 200.0
The remainder is 47 after subtracting 0 from 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 450

Step 6:
450 goes into 472 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 2001.0
The remainder is 22 after subtracting 450 from 472.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 450

Step 7:
450 goes into 225 0 times with a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 20010.0
The remainder is 225 after subtracting 0 from 225.
Take the next digit (1) from the dividend and append it to 225, then repeat: 2251 / 450

Let's proceed to step 8:
450 can be fit into 2251 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 200105.0
If we take 2250 away from 2251, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 450, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 200105.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 450, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 200105.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 200105.0 with a remaining 0.1.
