646824 ÷ 98 
Our goal is to divide 646824 by 98.

Advancing to step 1:
The number 98 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 98

Moving on to step 2:
If we divide 64 by 98, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 98

Let's proceed to step 3:
646 divided by 98 is 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 588 from 646 and we're left with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 98

Let's proceed to step 4:
98 goes into 588 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 588 from 588 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 98

Advancing to step 5:
98 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 98

Going ahead to step 6:
98 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 6600.0
Subtract 0 from 24 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
98 can be fit into 240 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6600.2
Subtracting 196 from 240 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
98 can be fit into 440 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 6600.24
If we take 392 away from 440, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
98 can be fit into 480 4 times, resulting in a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 6600.244
Subtract 392 from 480 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Our division results in 6600.244 with a remaining 0.0088.
