99744580 divided by 3 
We're looking to find how many times 3 goes into 99744580.

On to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 9 away from 9, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Let's proceed to step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Step 3:
7 divided by 3 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 332.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Let's proceed to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 3324.0
Subtracting 12 from 14 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Advancing to step 5:
24 divided by 3 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 33248.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Moving on to step 6:
3 can be fit into 5 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 332481.0
If we subtract 3 from 5, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Step 7:
28 divided by 3 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3324819.0
Subtracting 27 from 28 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 33248193.0
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 33248193.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 33248193.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 33248193.33 with a remainder of 0.001.
