Let's divide 80399120 by 396
We want to figure out the number of times 80399120 can be divided by 396.

Advancing 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
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 396

Moving on to step 2:
The number 396 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 396

Going ahead to step 3:
If we divide 803 by 396, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 792 from 803 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 396

Let's proceed to step 4:
When dividing 119 by 396, we get 0 with a remainder of 119.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 119, we end up with 119.
Grab the next digit (9) from the dividend, add it to 119, then carry on: 1199 / 396

On to step 5:
If we divide 1199 by 396, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Deduct 1188 from 1199 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 396

Step 6:
396 goes into 111 0 times with a remainder of 111.
Use 0 as the next digit of our solution. 
Result so far: 2030.0
Subtract 0 from 111 to get 111.
Bring next digit (2) of the dividend behind the 111 and repeat the process: 1112 / 396

Advancing to step 7:
396 goes into 1112 2 times with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 20302.0
The remainder is 320 after subtracting 792 from 1112.
Grab the next digit (0) from the dividend, add it to 320, then carry on: 3200 / 396

Moving on to step 8:
3200 divided by 396 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 203028.0
The remainder is 32 after subtracting 3168 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
396 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 203028.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
If we divide 3200 by 396, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 203028.08
The remainder is 32 after subtracting 3168 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 396 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 203028.08
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
If we divide 3200 by 396, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 203028.0808
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
396 can be fit into 320 0 times, resulting in a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 203028.0808
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
396 goes into 3200 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 203028.080808
Subtracting 3168 from 3200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
396 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 203028.080808
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 16:
396 goes into 3200 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 203028.08080808
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 203028.08080808 with a balance of 3.2e-08.
