We look at the division of 343915 by 98 
We want to divide 343915 by 98.

Going ahead to step 1:
The number 98 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 98

Moving on to step 2:
34 divided by 98 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 98

On to step 3:
98 goes into 343 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 294 from 343 to get 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 98

On to step 4:
98 goes into 499 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 490 from 499 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 98

Moving on to step 5:
When dividing 91 by 98, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 98

Going ahead to step 6:
98 can be fit into 915 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 3509.0
Subtract 882 from 915 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
When dividing 330 by 98, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 3509.3
If we take 294 away from 330, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
98 can be fit into 360 3 times, resulting in a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 3509.33
Deduct 294 from 360 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 3509.33 with a remaining 0.066.
