We look at the division of 390792 by 98 
Let's see how many times 98 fits into 390792.

Advancing to step 1:
98 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 98

Let's proceed to step 2:
If we divide 39 by 98, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 98

Step 3:
The number 98 fits into 390 3 times, leaving a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 294 from 390 leaves us with 96.
Bring next digit (7) of the dividend behind the 96 and repeat the process: 967 / 98

On to step 4:
967 divided by 98 is 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 882 from 967, we get 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 98

Step 5:
If we divide 859 by 98, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtract 784 from 859 to get 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 98

On to step 6:
If we divide 752 by 98, we get 7 and a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 3987.0
Deduct 686 from 752 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.

Step 7:
If we divide 660 by 98, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 3987.6
Deduct 588 from 660 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
The number 98 fits into 720 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 3987.67
Deduct 686 from 720 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 98, we get 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 3987.673
If we take 294 away from 340, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 98, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 3987.6734
Subtracting 392 from 460 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
98 can be fit into 680 6 times, resulting in a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 3987.67346
Deduct 588 from 680 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 12:
If we divide 920 by 98, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 3987.673469
Subtracting 882 from 920 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
98 can be fit into 380 3 times, resulting in a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 3987.6734693
If we subtract 294 from 380, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 14:
When dividing 860 by 98, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 3987.67346938
Subtract 784 from 860 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 3987.67346938 with a remaining 7.6e-08.
