We look at the division of 663809 by 98 
Our goal is to divide 663809 by 98.

Moving on to step 1:
If we divide 6 by 98, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 98

On to step 2:
98 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 98

On to step 3:
98 can be fit into 663 6 times, resulting in a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 588 from 663 and we're left with 75.
Bring next digit (8) of the dividend behind the 75 and repeat the process: 758 / 98

Advancing to step 4:
If we divide 758 by 98, we get 7 and a remainder of 72.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 686 from 758 and we're left with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 98

Going ahead to step 5:
The number 98 fits into 720 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 677.0
If we subtract 686 from 720, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 98

Step 6:
98 can be fit into 349 3 times, resulting in a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 6773.0
If we subtract 294 from 349, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
The number 98 fits into 550 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 6773.5
If we take 490 away from 550, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
When dividing 600 by 98, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6773.56
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
98 can be fit into 120 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 6773.561
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 98, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 6773.5612
Subtracting 196 from 220 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 98 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6773.56122
The remainder is 44 after subtracting 196 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 6773.56122 and a remainder of 4.4e-05.
