98069755 ÷ 321 
We want to divide 98069755 by 321.

Step 1:
The number 321 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 321

Going ahead to step 2:
98 divided by 321 is 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 321

On to step 3:
980 divided by 321 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 963 from 980 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 321

Advancing to step 4:
176 divided by 321 is 0 with a remainder of 176.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 176, we get 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 321

Moving on to step 5:
321 can be fit into 1769 5 times, resulting in a remainder of 164.
The next digit of our result is 5. 
Result so far: 305.0
Subtract 1605 from 1769 to get 164.
Fetch the next digit (7) from the dividend, attach it to 164 and continue: 1647 / 321

Advancing to step 6:
1647 divided by 321 is 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055.0
Subtracting 1605 from 1647 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 321

On to step 7:
If we divide 425 by 321, we get 1 and a remainder of 104.
The next digit of our result is 1. 
Result so far: 30551.0
The remainder is 104 after subtracting 321 from 425.
Grab the next digit (5) from the dividend, add it to 104, then carry on: 1045 / 321

Let's proceed to step 8:
321 can be fit into 1045 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 305513.0
Deduct 963 from 1045 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
If we divide 820 by 321, we get 2 and a remainder of 178.
The next digit of our result is 2. 
Result so far: 305513.2
Subtract 642 from 820 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
If we divide 1780 by 321, we get 5 and a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 305513.25
Subtract 1605 from 1780 to 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.

Going ahead to step 11:
321 goes into 1750 5 times with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 305513.255
If we take 1605 away from 1750, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 305513.255, with a leftover of 0.0145.
