We look at the division of 76390809 by 649 
We want to figure out the number of times 76390809 can be divided by 649.

Moving on to step 1:
7 divided by 649 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 649

Step 2:
If we divide 76 by 649, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 649

Going ahead to step 3:
The number 649 fits into 763 1 times, leaving a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 649 from 763 and we're left with 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 649

Moving on to step 4:
When dividing 1149 by 649, we get 1 with a remainder of 500.
The next digit of our result is 1. 
Result so far: 11.0
If we take 649 away from 1149, we end up with 500.
Append the next digit (0) from the dividend to 500 and continue with: 5000 / 649

Step 5:
When dividing 5000 by 649, we get 7 with a remainder of 457.
Put 7 as the next digit of the answer. 
Result so far: 117.0
The remainder is 457 after subtracting 4543 from 5000.
Append the next digit (8) from the dividend to 457 and continue with: 4578 / 649

Going ahead to step 6:
4578 divided by 649 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 1177.0
Subtracting 4543 from 4578 leaves us with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 649

Step 7:
When dividing 350 by 649, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 11770.0
The remainder is 350 after subtracting 0 from 350.
Grab the next digit (9) from the dividend, add it to 350, then carry on: 3509 / 649

On to step 8:
If we divide 3509 by 649, we get 5 and a remainder of 264.
The number 5 becomes the next digit in our result. 
Result so far: 117705.0
If we subtract 3245 from 3509, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 9:
When dividing 2640 by 649, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 117705.4
Subtract 2596 from 2640 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
649 can be fit into 440 0 times, resulting in a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 117705.4
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
649 can be fit into 4400 6 times, resulting in a remainder of 506.
The next digit of our result is 6. 
Result so far: 117705.406
If we take 3894 away from 4400, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 12:
If we divide 5060 by 649, we get 7 and a remainder of 517.
Record the quotient 7 as the next digit in the result. 
Result so far: 117705.4067
Subtract 4543 from 5060 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Moving on to step 13:
5170 divided by 649 is 7 with a remainder of 627.
Record the quotient 7 as the next digit in the result. 
Result so far: 117705.40677
Subtracting 4543 from 5170 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

The final outcome is 117705.40677, with a leftover of 0.000627.
