We divide 97104435 by 129
We're looking to find how many times 129 goes into 97104435.

Let's proceed to step 1:
The number 129 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 129

Step 2:
The number 129 fits into 97 0 times, leaving a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 129

Moving on to step 3:
When dividing 971 by 129, we get 7 with a remainder of 68.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 903 from 971 leaves us with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 129

On to step 4:
The number 129 fits into 680 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 75.0
If we take 645 away from 680, we end up with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 129

On to step 5:
The number 129 fits into 354 2 times, leaving a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
The remainder is 96 after subtracting 258 from 354.
Fetch the next digit (4) from the dividend, attach it to 96 and continue: 964 / 129

Advancing to step 6:
129 goes into 964 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7527.0
Subtract 903 from 964 to get 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 129

Going ahead to step 7:
When dividing 613 by 129, we get 4 with a remainder of 97.
Write down 4 as next digit of the result. 
Result so far: 75274.0
Subtracting 516 from 613 leaves us with 97.
Include the next digit (5) from the dividend after 97, then repeat: 975 / 129

Going ahead to step 8:
When dividing 975 by 129, we get 7 with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 752747.0
Subtract 903 from 975 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 129, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 752747.5
Subtracting 645 from 720 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
129 can be fit into 750 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 752747.55
Subtract 645 from 750 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 752747.55, with a leftover of 0.105.
