80440879 divided by 396 
We want to divide 80440879 by 396.

Moving on to step 1:
8 divided by 396 is 0 with 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 (0) of the dividend behind the 8 and repeat the process: 80 / 396

Step 2:
80 divided by 396 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 396

Step 3:
The number 396 fits into 804 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 792 from 804, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 396

Step 4:
If we divide 124 by 396, we get 0 and a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 124 after subtracting 0 from 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 396

On to step 5:
If we divide 1240 by 396, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we subtract 1188 from 1240, we get 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 396

Going ahead to step 6:
396 goes into 528 1 times with a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 2031.0
Subtracting 396 from 528 leaves us with 132.
Include the next digit (7) from the dividend after 132, then repeat: 1327 / 396

Step 7:
1327 divided by 396 is 3 with a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 20313.0
Subtract 1188 from 1327 to get 139.
Include the next digit (9) from the dividend after 139, then repeat: 1399 / 396

Step 8:
If we divide 1399 by 396, we get 3 and a remainder of 211.
The next digit of our result is 3. 
Result so far: 203133.0
If we subtract 1188 from 1399, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
The number 396 fits into 2110 5 times, leaving a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 203133.5
If we subtract 1980 from 2110, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
The number 396 fits into 1300 3 times, leaving a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 203133.53
Subtracting 1188 from 1300 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
396 goes into 1120 2 times with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 203133.532
Deduct 792 from 1120 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
396 can be fit into 3280 8 times, resulting in a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 203133.5328
Deduct 3168 from 3280 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
1120 divided by 396 is 2 with a remainder of 328.
Write down 2 as next digit of the result. 
Result so far: 203133.53282
The remainder is 328 after subtracting 792 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 14:
The number 396 fits into 3280 8 times, leaving a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 203133.532828
Subtract 3168 from 3280 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
1120 divided by 396 is 2 with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 203133.5328282
If we take 792 away from 1120, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 16:
3280 divided by 396 is 8 with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 203133.53282828
If we take 3168 away from 3280, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 203133.53282828 and a remainder of 1.12e-07.
