399399 divided by 98 
Our goal is to divide 399399 by 98.

Going ahead to step 1:
If we divide 3 by 98, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 98

Step 2:
When dividing 39 by 98, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 98

Step 3:
399 divided by 98 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 392 from 399, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 98

Let's proceed to step 4:
The number 98 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 73 to get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 98

Advancing to step 5:
98 goes into 739 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 407.0
Deduct 686 from 739 and we're left with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 98

Going ahead to step 6:
98 goes into 539 5 times with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 4075.0
Subtracting 490 from 539 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
If we divide 490 by 98, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4075.5
If we subtract 490 from 490, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 98 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4075.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
98 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4075.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4075.5 and a remainder of 0.0.
