We're dividing 90980446 by 449 
We want to figure out the number of times 90980446 can be divided by 449.

Going ahead to step 1:
If we divide 9 by 449, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 449

Step 2:
When dividing 90 by 449, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 449

On to step 3:
The number 449 fits into 909 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 898 from 909 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 449

On to step 4:
449 can be fit into 118 0 times, resulting in a remainder of 118.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 118 and we're left with 118.
Take the next digit (0) from the dividend and append it to 118, then repeat: 1180 / 449

Going ahead to step 5:
If we divide 1180 by 449, we get 2 and a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we take 898 away from 1180, we end up with 282.
Grab the next digit (4) from the dividend, add it to 282, then carry on: 2824 / 449

On to step 6:
449 goes into 2824 6 times with a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 2026.0
Deduct 2694 from 2824 and we're left with 130.
Bring next digit (4) of the dividend behind the 130 and repeat the process: 1304 / 449

Advancing to step 7:
1304 divided by 449 is 2 with a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 20262.0
If we subtract 898 from 1304, we get 406.
Append the next digit (6) from the dividend to 406 and continue with: 4066 / 449

On to step 8:
449 goes into 4066 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 202629.0
Deduct 4041 from 4066 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
449 can be fit into 250 0 times, resulting in a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 202629.0
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
When dividing 2500 by 449, we get 5 with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 202629.05
Deduct 2245 from 2500 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 11:
449 goes into 2550 5 times with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 202629.055
If we take 2245 away from 2550, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 202629.055 and a remainder of 0.0305.
