We're dividing 76528499 by 449 
We want to divide 76528499 by 449.

On to step 1:
449 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 449

Advancing to step 2:
When dividing 76 by 449, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 449

Advancing to step 3:
If we divide 765 by 449, we get 1 and a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 449 from 765, we get 316.
Include the next digit (2) from the dividend after 316, then repeat: 3162 / 449

Moving on to step 4:
449 can be fit into 3162 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 3143 from 3162 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 449

Advancing to step 5:
449 can be fit into 198 0 times, resulting in a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 198 and we're left with 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 449

On to step 6:
The number 449 fits into 1984 4 times, leaving a remainder of 188.
The next digit of our result is 4. 
Result so far: 1704.0
If we subtract 1796 from 1984, we get 188.
Append the next digit (9) from the dividend to 188 and continue with: 1889 / 449

Moving on to step 7:
1889 divided by 449 is 4 with a remainder of 93.
Use 4 as the next digit of our solution. 
Result so far: 17044.0
The remainder is 93 after subtracting 1796 from 1889.
Take the next digit (9) from the dividend and append it to 93, then repeat: 939 / 449

Advancing to step 8:
The number 449 fits into 939 2 times, leaving a remainder of 41.
The next digit of our result is 2. 
Result so far: 170442.0
Deduct 898 from 939 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
The number 449 fits into 410 0 times, leaving a remainder of 410.
The next digit of our result is 0. 
Result so far: 170442.0
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
If we divide 4100 by 449, we get 9 and a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 170442.09
If we subtract 4041 from 4100, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 11:
449 can be fit into 590 1 times, resulting in a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 170442.091
Subtract 449 from 590 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 12:
When dividing 1410 by 449, we get 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 170442.0913
If we take 1347 away from 1410, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
When dividing 630 by 449, we get 1 with a remainder of 181.
The next digit of our result is 1. 
Result so far: 170442.09131
Subtracting 449 from 630 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 14:
The number 449 fits into 1810 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 170442.091314
The remainder is 14 after subtracting 1796 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
449 goes into 140 0 times with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 170442.091314
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
The number 449 fits into 1400 3 times, leaving a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 170442.09131403
The remainder is 53 after subtracting 1347 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 170442.09131403, with a leftover of 5.3e-08.
