We look at the division of 780799 by 98 
We want to figure out the number of times 780799 can be divided by 98.

Let's proceed to step 1:
If we divide 7 by 98, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 98

On to step 2:
The number 98 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 98

Step 3:
98 goes into 780 7 times with a remainder of 94.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 686 from 780, we get 94.
Take the next digit (7) from the dividend and append it to 94, then repeat: 947 / 98

Going ahead to step 4:
When dividing 947 by 98, we get 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 79.0
Deduct 882 from 947 and we're left with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 98

Going ahead to step 5:
98 goes into 659 6 times with a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 796.0
Deduct 588 from 659 and we're left with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 98

On to step 6:
98 can be fit into 719 7 times, resulting in a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 7967.0
Subtract 686 from 719 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 98 fits into 330 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 7967.3
Subtracting 294 from 330 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
If we divide 360 by 98, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 7967.33
Deduct 294 from 360 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 7967.33, with a leftover of 0.066.
