We look at the division of 678580 by 98 
Let's see how many times 98 fits into 678580.

Advancing to step 1:
When dividing 6 by 98, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 98

Step 2:
67 divided by 98 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 98

Going ahead to step 3:
If we divide 678 by 98, we get 6 and a remainder of 90.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 90 after subtracting 588 from 678.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 98

Going ahead to step 4:
The number 98 fits into 905 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 882 from 905 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 98

Step 5:
98 can be fit into 238 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 692.0
If we subtract 196 from 238, we get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 98

Going ahead to step 6:
420 divided by 98 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 6924.0
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
280 divided by 98 is 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 6924.2
If we subtract 196 from 280, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
If we divide 840 by 98, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 6924.28
If we subtract 784 from 840, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 98, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 6924.285
Deduct 490 from 560 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 98, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 6924.2857
If we subtract 686 from 700, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
98 goes into 140 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 6924.28571
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
The number 98 fits into 420 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 6924.285714
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
98 can be fit into 280 2 times, resulting in a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 6924.2857142
Subtracting 196 from 280 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
The number 98 fits into 840 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 6924.28571428
The remainder is 56 after subtracting 784 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 6924.28571428 with a balance of 5.6e-08.
