80398816 ÷ 798 
We want to figure out the number of times 80398816 can be divided by 798.

Let's proceed to step 1:
798 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 798

Step 2:
The number 798 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 798

Step 3:
798 goes into 803 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 798 from 803 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 798

Step 4:
798 goes into 59 0 times with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 59 after subtracting 0 from 59.
Fetch the next digit (8) from the dividend, attach it to 59 and continue: 598 / 798

Let's proceed to step 5:
When dividing 598 by 798, we get 0 with a remainder of 598.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 598 leaves us with 598.
Take the next digit (8) from the dividend and append it to 598, then repeat: 5988 / 798

Moving on to step 6:
The number 798 fits into 5988 7 times, leaving a remainder of 402.
Write down 7 as next digit of the result. 
Result so far: 1007.0
The remainder is 402 after subtracting 5586 from 5988.
Include the next digit (1) from the dividend after 402, then repeat: 4021 / 798

Step 7:
4021 divided by 798 is 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 10075.0
Subtracting 3990 from 4021 leaves us with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 798

Let's proceed to step 8:
316 divided by 798 is 0 with a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 100750.0
Deduct 0 from 316 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 9:
798 can be fit into 3160 3 times, resulting in a remainder of 766.
The number 3 becomes the next digit in our result. 
Result so far: 100750.3
Subtracting 2394 from 3160 leaves us with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Going ahead to step 10:
798 can be fit into 7660 9 times, resulting in a remainder of 478.
Record the quotient 9 as the next digit in the result. 
Result so far: 100750.39
The remainder is 478 after subtracting 7182 from 7660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 11:
If we divide 4780 by 798, we get 5 and a remainder of 790.
The next digit of our result is 5. 
Result so far: 100750.395
If we take 3990 away from 4780, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Let's proceed to step 12:
798 goes into 7900 9 times with a remainder of 718.
The number 9 becomes the next digit in our result. 
Result so far: 100750.3959
If we subtract 7182 from 7900, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 13:
798 goes into 7180 8 times with a remainder of 796.
Use 8 as the next digit of our solution. 
Result so far: 100750.39598
Deduct 6384 from 7180 and we're left with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Let's proceed to step 14:
The number 798 fits into 7960 9 times, leaving a remainder of 778.
The number 9 becomes the next digit in our result. 
Result so far: 100750.395989
The remainder is 778 after subtracting 7182 from 7960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

On to step 15:
If we divide 7780 by 798, we get 9 and a remainder of 598.
Use 9 as the next digit of our solution. 
Result so far: 100750.3959899
If we subtract 7182 from 7780, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

In conclusion, the division gives 100750.3959899 with a balance of 5.98e-06.
