We look at the division of 64385679 by 649 
We want to figure out the number of times 64385679 can be divided by 649.

Step 1:
6 divided by 649 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 649

Step 2:
When dividing 64 by 649, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 649

Step 3:
The number 649 fits into 643 0 times, leaving a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 643 leaves us with 643.
Include the next digit (8) from the dividend after 643, then repeat: 6438 / 649

Advancing to step 4:
The number 649 fits into 6438 9 times, leaving a remainder of 597.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 5841 from 6438 and we're left with 597.
Include the next digit (5) from the dividend after 597, then repeat: 5975 / 649

Step 5:
If we divide 5975 by 649, we get 9 and a remainder of 134.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 5841 from 5975 to get 134.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 649

Going ahead to step 6:
When dividing 1346 by 649, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 992.0
Deduct 1298 from 1346 and we're left with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 649

Step 7:
649 can be fit into 487 0 times, resulting in a remainder of 487.
The next digit of our result is 0. 
Result so far: 9920.0
If we subtract 0 from 487, we get 487.
Bring next digit (9) of the dividend behind the 487 and repeat the process: 4879 / 649

Going ahead to step 8:
649 goes into 4879 7 times with a remainder of 336.
Use 7 as the next digit of our solution. 
Result so far: 99207.0
Subtracting 4543 from 4879 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 9:
649 goes into 3360 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 99207.5
Subtracting 3245 from 3360 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
When dividing 1150 by 649, we get 1 with a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 99207.51
If we subtract 649 from 1150, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
649 can be fit into 5010 7 times, resulting in a remainder of 467.
The next digit of our result is 7. 
Result so far: 99207.517
The remainder is 467 after subtracting 4543 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 12:
The number 649 fits into 4670 7 times, leaving a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 99207.5177
Subtract 4543 from 4670 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Our division results in 99207.5177 with a remaining 0.00127.
