We divide 399731 by 98
Let's see how many times 98 fits into 399731.

On to step 1:
When dividing 3 by 98, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 98

Let's proceed 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
Deduct 0 from 39 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 98

Let's proceed to step 3:
98 can be fit into 399 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 392 away from 399, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 98

Step 4:
77 divided by 98 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 98

Step 5:
The number 98 fits into 773 7 times, leaving a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Subtracting 686 from 773 leaves us with 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 98

On to step 6:
The number 98 fits into 871 8 times, leaving a remainder of 87.
The next digit of our result is 8. 
Result so far: 4078.0
Subtracting 784 from 871 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 7:
If we divide 870 by 98, we get 8 and a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 4078.8
If we subtract 784 from 870, 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.

Advancing to step 8:
98 goes into 860 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 4078.88
Subtracting 784 from 860 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 4078.88 with a remainder of 0.076.
