Let's divide 86104319 by 98
We want to divide 86104319 by 98.

Advancing to step 1:
When dividing 8 by 98, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 98

Going ahead to step 2:
The number 98 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 98

On to step 3:
The number 98 fits into 861 8 times, leaving a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 784 from 861 leaves us with 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 98

Moving on to step 4:
If we divide 770 by 98, we get 7 and a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
The remainder is 84 after subtracting 686 from 770.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 98

Let's proceed to step 5:
844 divided by 98 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
Deduct 784 from 844 and we're left with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 98

Advancing to step 6:
603 divided by 98 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 8786.0
Subtract 588 from 603 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 98

Going ahead to step 7:
The number 98 fits into 151 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 87861.0
If we take 98 away from 151, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 98

On to step 8:
98 goes into 539 5 times with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 878615.0
Subtracting 490 from 539 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
The number 98 fits into 490 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 878615.5
The remainder is 0 after subtracting 490 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 98, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 878615.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 98 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 878615.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 878615.5 with a balance of 0.0.
