We're dividing 65486091 by 449 
Let's see how many times 449 fits into 65486091.

Moving on to step 1:
When dividing 6 by 449, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 449

Going ahead to step 2:
When dividing 65 by 449, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 449

Advancing to step 3:
449 can be fit into 654 1 times, resulting in a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 449 from 654 leaves us with 205.
Take the next digit (8) from the dividend and append it to 205, then repeat: 2058 / 449

Let's proceed to step 4:
When dividing 2058 by 449, we get 4 with a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1796 from 2058 leaves us with 262.
Bring next digit (6) of the dividend behind the 262 and repeat the process: 2626 / 449

Step 5:
449 can be fit into 2626 5 times, resulting in a remainder of 381.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 2245 away from 2626, we end up with 381.
Take the next digit (0) from the dividend and append it to 381, then repeat: 3810 / 449

On to step 6:
449 goes into 3810 8 times with a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 1458.0
If we take 3592 away from 3810, we end up with 218.
Grab the next digit (9) from the dividend, add it to 218, then carry on: 2189 / 449

Advancing to step 7:
The number 449 fits into 2189 4 times, leaving a remainder of 393.
Use 4 as the next digit of our solution. 
Result so far: 14584.0
The remainder is 393 after subtracting 1796 from 2189.
Grab the next digit (1) from the dividend, add it to 393, then carry on: 3931 / 449

Going ahead to step 8:
449 can be fit into 3931 8 times, resulting in a remainder of 339.
Record the quotient 8 as the next digit in the result. 
Result so far: 145848.0
Subtract 3592 from 3931 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 9:
When dividing 3390 by 449, we get 7 with a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 145848.7
Subtracting 3143 from 3390 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 10:
449 goes into 2470 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 145848.75
Deduct 2245 from 2470 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
449 goes into 2250 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 145848.755
If we take 2245 away from 2250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 145848.755 and a remainder of 0.0005.
