We're dividing 671680 by 98 
We're looking to find how many times 98 goes into 671680.

Step 1:
If we divide 6 by 98, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 98

On to step 2:
98 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 98

Advancing to step 3:
When dividing 671 by 98, we get 6 with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 588 from 671 to get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 98

Moving on to step 4:
When dividing 836 by 98, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 784 from 836 leaves us with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 98

Let's proceed to step 5:
The number 98 fits into 528 5 times, leaving a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 685.0
Deduct 490 from 528 and we're left with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 98

Let's proceed to step 6:
When dividing 380 by 98, we get 3 with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 6853.0
Subtract 294 from 380 to 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.

Moving on to step 7:
98 can be fit into 860 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 6853.8
The remainder is 76 after subtracting 784 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
760 divided by 98 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 6853.87
The remainder is 74 after subtracting 686 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
When dividing 740 by 98, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 6853.877
Subtracting 686 from 740 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 6853.877 with a remainder of 0.0054.
