96990129 divided by 300 
We're looking to find how many times 300 goes into 96990129.

On to step 1:
9 divided by 300 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 300

Advancing to step 2:
96 divided by 300 is 0 with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Bring next digit (9) of the dividend behind the 96 and repeat the process: 969 / 300

Advancing to step 3:
300 goes into 969 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 900 from 969 to get 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 300

Moving on to step 4:
300 goes into 699 2 times with a remainder of 99.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 600 from 699 leaves us with 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 300

Step 5:
When dividing 990 by 300, we get 3 with a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 323.0
Subtract 900 from 990 to get 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 300

Advancing to step 6:
The number 300 fits into 901 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3233.0
Deduct 900 from 901 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 300

Moving on to step 7:
300 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 32330.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 300

Moving on to step 8:
300 goes into 129 0 times with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 323300.0
The remainder is 129 after subtracting 0 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 9:
300 goes into 1290 4 times with a remainder of 90.
The next digit of our result is 4. 
Result so far: 323300.4
Subtract 1200 from 1290 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
When dividing 900 by 300, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 323300.43
The remainder is 0 after subtracting 900 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 300 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 323300.43
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.

Step 12:
The number 300 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 323300.43
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.

The quotient of the division is 323300.43, and the remainder is 0.0.
