399504 ÷ 98 
We want to divide 399504 by 98.

Let's proceed 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 98

Advancing to step 2:
The number 98 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 98

Advancing to step 3:
The number 98 fits into 399 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 7 after subtracting 392 from 399.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 98

Let's proceed to step 4:
75 divided by 98 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 75, we end up with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 98

Moving on to step 5:
750 divided by 98 is 7 with a remainder of 64.
The next digit of our result is 7. 
Result so far: 407.0
If we subtract 686 from 750, we get 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 98

On to step 6:
98 can be fit into 644 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 4076.0
Subtract 588 from 644 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
The number 98 fits into 560 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 4076.5
Subtracting 490 from 560 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
98 can be fit into 700 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 4076.57
Subtracting 686 from 700 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
98 can be fit into 140 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 4076.571
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
98 goes into 420 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4076.5714
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 98 fits into 280 2 times, leaving a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 4076.57142
If we take 196 away from 280, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
If we divide 840 by 98, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 4076.571428
Deduct 784 from 840 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
98 can be fit into 560 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4076.5714285
Subtract 490 from 560 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
When dividing 700 by 98, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 4076.57142857
If we subtract 686 from 700, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 4076.57142857, and the remainder is 1.4e-08.
