Let's divide 98799890 by 305
We want to divide 98799890 by 305.

Going ahead to step 1:
When dividing 9 by 305, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 305

Moving on to step 2:
When dividing 98 by 305, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 305

Moving on to step 3:
If we divide 987 by 305, we get 3 and a remainder of 72.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 915 from 987 and we're left with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 305

Advancing to step 4:
The number 305 fits into 729 2 times, leaving a remainder of 119.
The next digit of our result is 2. 
Result so far: 32.0
If we take 610 away from 729, we end up with 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 305

Advancing to step 5:
When dividing 1199 by 305, we get 3 with a remainder of 284.
Write down 3 as next digit of the result. 
Result so far: 323.0
The remainder is 284 after subtracting 915 from 1199.
Fetch the next digit (8) from the dividend, attach it to 284 and continue: 2848 / 305

On to step 6:
When dividing 2848 by 305, we get 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 3239.0
Deduct 2745 from 2848 and we're left with 103.
Include the next digit (9) from the dividend after 103, then repeat: 1039 / 305

Let's proceed to step 7:
When dividing 1039 by 305, we get 3 with a remainder of 124.
Put 3 as the next digit of the answer. 
Result so far: 32393.0
If we subtract 915 from 1039, we get 124.
Include the next digit (0) from the dividend after 124, then repeat: 1240 / 305

Let's proceed to step 8:
When dividing 1240 by 305, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 323934.0
If we take 1220 away from 1240, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
305 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 323934.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
The number 305 fits into 2000 6 times, leaving a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 323934.06
If we take 1830 away from 2000, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
1700 divided by 305 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 323934.065
If we subtract 1525 from 1700, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 12:
The number 305 fits into 1750 5 times, leaving a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 323934.0655
Subtracting 1525 from 1750 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

After the division, we end up with 323934.0655 and a remainder of 0.00225.
