We're dividing 76865875 by 449 
Our goal is to divide 76865875 by 449.

Going ahead to step 1:
7 divided by 449 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 449

On to step 2:
76 divided by 449 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 449

Advancing to step 3:
449 can be fit into 768 1 times, resulting in a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 449 from 768 leaves us with 319.
Include the next digit (6) from the dividend after 319, then repeat: 3196 / 449

Moving on to step 4:
When dividing 3196 by 449, we get 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3143 from 3196 leaves us with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 449

Moving on to step 5:
If we divide 535 by 449, we get 1 and a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 171.0
Deduct 449 from 535 and we're left with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 449

On to step 6:
449 goes into 868 1 times with a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 1711.0
The remainder is 419 after subtracting 449 from 868.
Bring next digit (7) of the dividend behind the 419 and repeat the process: 4197 / 449

Moving on to step 7:
449 goes into 4197 9 times with a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 17119.0
Deduct 4041 from 4197 and we're left with 156.
Grab the next digit (5) from the dividend, add it to 156, then carry on: 1565 / 449

Going ahead to step 8:
1565 divided by 449 is 3 with a remainder of 218.
Record the quotient 3 as the next digit in the result. 
Result so far: 171193.0
If we subtract 1347 from 1565, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 9:
449 can be fit into 2180 4 times, resulting in a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 171193.4
The remainder is 384 after subtracting 1796 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
449 goes into 3840 8 times with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 171193.48
The remainder is 248 after subtracting 3592 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 11:
449 can be fit into 2480 5 times, resulting in a remainder of 235.
The next digit of our result is 5. 
Result so far: 171193.485
Subtracting 2245 from 2480 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 12:
449 can be fit into 2350 5 times, resulting in a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 171193.4855
The remainder is 105 after subtracting 2245 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 171193.4855 with a remainder of 0.00105.
