646433 ÷ 98 
Let's see how many times 98 fits into 646433.

On to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 98

Advancing to step 2:
When dividing 64 by 98, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 98

Step 3:
646 divided by 98 is 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 58 after subtracting 588 from 646.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 98

Moving on to step 4:
98 can be fit into 584 5 times, resulting in a remainder of 94.
The next digit of our result is 5. 
Result so far: 65.0
The remainder is 94 after subtracting 490 from 584.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 98

Step 5:
When dividing 943 by 98, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 659.0
If we take 882 away from 943, we end up with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 98

Let's proceed to step 6:
613 divided by 98 is 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 6596.0
If we subtract 588 from 613, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 98, we get 2 and a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 6596.2
The remainder is 54 after subtracting 196 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
98 goes into 540 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6596.25
The remainder is 50 after subtracting 490 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 98 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 6596.255
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 6596.255, with a leftover of 0.001.
