We're dividing 23130729 by 649 
We're looking to find how many times 649 goes into 23130729.

Advancing to step 1:
649 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 649

Step 2:
When dividing 23 by 649, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 649

On to step 3:
231 divided by 649 is 0 with a remainder of 231.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 231 and we're left with 231.
Take the next digit (3) from the dividend and append it to 231, then repeat: 2313 / 649

Going ahead to step 4:
The number 649 fits into 2313 3 times, leaving a remainder of 366.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1947 from 2313 and we're left with 366.
Bring next digit (0) of the dividend behind the 366 and repeat the process: 3660 / 649

On to step 5:
649 goes into 3660 5 times with a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 3245 from 3660 leaves us with 415.
Fetch the next digit (7) from the dividend, attach it to 415 and continue: 4157 / 649

On to step 6:
The number 649 fits into 4157 6 times, leaving a remainder of 263.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
The remainder is 263 after subtracting 3894 from 4157.
Bring next digit (2) of the dividend behind the 263 and repeat the process: 2632 / 649

On to step 7:
2632 divided by 649 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3564.0
If we take 2596 away from 2632, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 649

Step 8:
When dividing 369 by 649, we get 0 with a remainder of 369.
Use 0 as the next digit of our solution. 
Result so far: 35640.0
Subtracting 0 from 369 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 9:
The number 649 fits into 3690 5 times, leaving a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 35640.5
Deduct 3245 from 3690 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 10:
The number 649 fits into 4450 6 times, leaving a remainder of 556.
Use 6 as the next digit of our solution. 
Result so far: 35640.56
Deduct 3894 from 4450 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 11:
When dividing 5560 by 649, we get 8 with a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 35640.568
The remainder is 368 after subtracting 5192 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 12:
3680 divided by 649 is 5 with a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 35640.5685
If we take 3245 away from 3680, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 13:
649 can be fit into 4350 6 times, resulting in a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 35640.56856
Deduct 3894 from 4350 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 14:
If we divide 4560 by 649, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 35640.568567
If we take 4543 away from 4560, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 15:
The number 649 fits into 170 0 times, leaving a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 35640.568567
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 16:
If we divide 1700 by 649, we get 2 and a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 35640.56856702
The remainder is 402 after subtracting 1298 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

After the division, we end up with 35640.56856702 and a remainder of 4.02e-07.
