We look at the division of 90781669 by 449 
Our goal is to divide 90781669 by 449.

On to step 1:
449 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 449

Step 2:
449 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (7) from the dividend after 90, then repeat: 907 / 449

On to step 3:
449 can be fit into 907 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 898 from 907, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 449

Advancing to step 4:
449 can be fit into 98 0 times, resulting in a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 98, we end up with 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 449

Advancing to step 5:
The number 449 fits into 981 2 times, leaving a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
Subtracting 898 from 981 leaves us with 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 449

Step 6:
836 divided by 449 is 1 with a remainder of 387.
Put 1 as the next digit of the answer. 
Result so far: 2021.0
The remainder is 387 after subtracting 449 from 836.
Include the next digit (6) from the dividend after 387, then repeat: 3876 / 449

Let's proceed to step 7:
3876 divided by 449 is 8 with a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 20218.0
Subtract 3592 from 3876 to get 284.
Append the next digit (9) from the dividend to 284 and continue with: 2849 / 449

On to step 8:
449 can be fit into 2849 6 times, resulting in a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 202186.0
The remainder is 155 after subtracting 2694 from 2849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
The number 449 fits into 1550 3 times, leaving a remainder of 203.
The next digit of our result is 3. 
Result so far: 202186.3
The remainder is 203 after subtracting 1347 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 10:
2030 divided by 449 is 4 with a remainder of 234.
Write down 4 as next digit of the result. 
Result so far: 202186.34
Deduct 1796 from 2030 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 11:
If we divide 2340 by 449, we get 5 and a remainder of 95.
The next digit of our result is 5. 
Result so far: 202186.345
Deduct 2245 from 2340 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
When dividing 950 by 449, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 202186.3452
Subtract 898 from 950 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
When dividing 520 by 449, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 202186.34521
If we take 449 away from 520, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
The number 449 fits into 710 1 times, leaving a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 202186.345211
Subtracting 449 from 710 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 202186.345211 and a remainder of 2.61e-05.
