23708408 ÷ 649 
We want to figure out the number of times 23708408 can be divided by 649.

On to step 1:
649 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 649

On to step 2:
649 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 649

Step 3:
The number 649 fits into 237 0 times, leaving a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 237 to get 237.
Fetch the next digit (0) from the dividend, attach it to 237 and continue: 2370 / 649

Let's proceed to step 4:
2370 divided by 649 is 3 with a remainder of 423.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1947 from 2370 to get 423.
Take the next digit (8) from the dividend and append it to 423, then repeat: 4238 / 649

Step 5:
If we divide 4238 by 649, we get 6 and a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 3894 from 4238, we get 344.
Append the next digit (4) from the dividend to 344 and continue with: 3444 / 649

On to step 6:
649 can be fit into 3444 5 times, resulting in a remainder of 199.
The next digit of our result is 5. 
Result so far: 365.0
Subtracting 3245 from 3444 leaves us with 199.
Take the next digit (0) from the dividend and append it to 199, then repeat: 1990 / 649

On to step 7:
649 goes into 1990 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 3653.0
The remainder is 43 after subtracting 1947 from 1990.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 649

Let's proceed to step 8:
438 divided by 649 is 0 with a remainder of 438.
Use 0 as the next digit of our solution. 
Result so far: 36530.0
If we subtract 0 from 438, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 9:
If we divide 4380 by 649, we get 6 and a remainder of 486.
Put 6 as the next digit of the answer. 
Result so far: 36530.6
Subtract 3894 from 4380 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 10:
649 goes into 4860 7 times with a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 36530.67
Subtract 4543 from 4860 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 11:
If we divide 3170 by 649, we get 4 and a remainder of 574.
The number 4 becomes the next digit in our result. 
Result so far: 36530.674
If we subtract 2596 from 3170, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 12:
5740 divided by 649 is 8 with a remainder of 548.
Use 8 as the next digit of our solution. 
Result so far: 36530.6748
Subtracting 5192 from 5740 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 13:
5480 divided by 649 is 8 with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 36530.67488
Deduct 5192 from 5480 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final result is 36530.67488 with a remainder of 0.000288.
