We're dividing 81986240 by 449 
We want to divide 81986240 by 449.

Moving on to step 1:
The number 449 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 449

Moving on to step 2:
If we divide 81 by 449, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 449

Going ahead to step 3:
If we divide 819 by 449, we get 1 and a remainder of 370.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 370 after subtracting 449 from 819.
Take the next digit (8) from the dividend and append it to 370, then repeat: 3708 / 449

Let's proceed to step 4:
The number 449 fits into 3708 8 times, leaving a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3592 from 3708 leaves us with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 449

Moving on to step 5:
If we divide 1166 by 449, we get 2 and a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
If we subtract 898 from 1166, we get 268.
Append the next digit (2) from the dividend to 268 and continue with: 2682 / 449

Let's proceed to step 6:
The number 449 fits into 2682 5 times, leaving a remainder of 437.
Put 5 as the next digit of the answer. 
Result so far: 1825.0
If we take 2245 away from 2682, we end up with 437.
Include the next digit (4) from the dividend after 437, then repeat: 4374 / 449

Let's proceed to step 7:
The number 449 fits into 4374 9 times, leaving a remainder of 333.
Write down 9 as next digit of the result. 
Result so far: 18259.0
Subtracting 4041 from 4374 leaves us with 333.
Grab the next digit (0) from the dividend, add it to 333, then carry on: 3330 / 449

On to step 8:
If we divide 3330 by 449, we get 7 and a remainder of 187.
The next digit of our result is 7. 
Result so far: 182597.0
If we subtract 3143 from 3330, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 9:
The number 449 fits into 1870 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 182597.4
The remainder is 74 after subtracting 1796 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
449 goes into 740 1 times with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 182597.41
Subtract 449 from 740 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 11:
449 can be fit into 2910 6 times, resulting in a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 182597.416
If we take 2694 away from 2910, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
The number 449 fits into 2160 4 times, leaving a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 182597.4164
Subtracting 1796 from 2160 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 13:
449 goes into 3640 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 182597.41648
Subtract 3592 from 3640 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
The number 449 fits into 480 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 182597.416481
Subtract 449 from 480 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 15:
When dividing 310 by 449, we get 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 182597.416481
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 16:
449 goes into 3100 6 times with a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 182597.41648106
If we take 2694 away from 3100, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The quotient of the division is 182597.41648106, and the remainder is 4.06e-07.
