We divide 2215221 by 450
We want to figure out the number of times 2215221 can be divided by 450.

Going ahead to step 1:
When dividing 2 by 450, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 450

Moving on to step 2:
The number 450 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 450

Let's proceed to step 3:
221 divided by 450 is 0 with a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 221 after subtracting 0 from 221.
Append the next digit (5) from the dividend to 221 and continue with: 2215 / 450

Step 4:
450 can be fit into 2215 4 times, resulting in a remainder of 415.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1800 from 2215 and we're left with 415.
Grab the next digit (2) from the dividend, add it to 415, then carry on: 4152 / 450

Advancing to step 5:
4152 divided by 450 is 9 with a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 102 after subtracting 4050 from 4152.
Include the next digit (2) from the dividend after 102, then repeat: 1022 / 450

On to step 6:
The number 450 fits into 1022 2 times, leaving a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
Deduct 900 from 1022 and we're left with 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 450

Going ahead to step 7:
450 goes into 1221 2 times with a remainder of 321.
Put 2 as the next digit of the answer. 
Result so far: 4922.0
If we take 900 away from 1221, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 8:
The number 450 fits into 3210 7 times, leaving a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 4922.7
If we subtract 3150 from 3210, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
600 divided by 450 is 1 with a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 4922.71
Deduct 450 from 600 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
450 can be fit into 1500 3 times, resulting in a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 4922.713
If we take 1350 away from 1500, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
If we divide 1500 by 450, we get 3 and a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 4922.7133
Subtracting 1350 from 1500 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 4922.7133 with a remainder of 0.0015.
