We're dividing 98579801 by 331 
We want to divide 98579801 by 331.

Step 1:
9 divided by 331 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 331

Step 2:
The number 331 fits into 98 0 times, leaving a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 331

Advancing to step 3:
985 divided by 331 is 2 with a remainder of 323.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 323 after subtracting 662 from 985.
Bring next digit (7) of the dividend behind the 323 and repeat the process: 3237 / 331

Let's proceed to step 4:
If we divide 3237 by 331, we get 9 and a remainder of 258.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 2979 from 3237 leaves us with 258.
Bring next digit (9) of the dividend behind the 258 and repeat the process: 2589 / 331

Let's proceed to step 5:
When dividing 2589 by 331, we get 7 with a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
If we take 2317 away from 2589, we end up with 272.
Take the next digit (8) from the dividend and append it to 272, then repeat: 2728 / 331

Advancing to step 6:
The number 331 fits into 2728 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 2978.0
The remainder is 80 after subtracting 2648 from 2728.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 331

Let's proceed to step 7:
800 divided by 331 is 2 with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 29782.0
If we subtract 662 from 800, we get 138.
Include the next digit (1) from the dividend after 138, then repeat: 1381 / 331

Going ahead to step 8:
When dividing 1381 by 331, we get 4 with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 297824.0
Deduct 1324 from 1381 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
570 divided by 331 is 1 with a remainder of 239.
The next digit of our result is 1. 
Result so far: 297824.1
If we subtract 331 from 570, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 10:
If we divide 2390 by 331, we get 7 and a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 297824.17
If we subtract 2317 from 2390, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
The number 331 fits into 730 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 297824.172
Subtract 662 from 730 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
331 can be fit into 680 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 297824.1722
If we subtract 662 from 680, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 297824.1722 with a remaining 0.00018.
