77064878 divided by 509 
Let's see how many times 509 fits into 77064878.

Let's proceed to step 1:
509 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 509

Advancing to step 2:
77 divided by 509 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 509

Let's proceed to step 3:
The number 509 fits into 770 1 times, leaving a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 509 from 770, we get 261.
Include the next digit (6) from the dividend after 261, then repeat: 2616 / 509

Step 4:
2616 divided by 509 is 5 with a remainder of 71.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2545 from 2616 to get 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 509

Let's proceed to step 5:
If we divide 714 by 509, we get 1 and a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we take 509 away from 714, we end up with 205.
Fetch the next digit (8) from the dividend, attach it to 205 and continue: 2058 / 509

Step 6:
If we divide 2058 by 509, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 1514.0
Deduct 2036 from 2058 and we're left with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 509

On to step 7:
The number 509 fits into 227 0 times, leaving a remainder of 227.
Use 0 as the next digit of our solution. 
Result so far: 15140.0
If we subtract 0 from 227, we get 227.
Bring next digit (8) of the dividend behind the 227 and repeat the process: 2278 / 509

Advancing to step 8:
When dividing 2278 by 509, we get 4 with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 151404.0
If we subtract 2036 from 2278, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 9:
509 can be fit into 2420 4 times, resulting in a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 151404.4
Deduct 2036 from 2420 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
The number 509 fits into 3840 7 times, leaving a remainder of 277.
Put 7 as the next digit of the answer. 
Result so far: 151404.47
Deduct 3563 from 3840 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 11:
509 can be fit into 2770 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 151404.475
If we subtract 2545 from 2770, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 12:
The number 509 fits into 2250 4 times, leaving a remainder of 214.
The number 4 becomes the next digit in our result. 
Result so far: 151404.4754
If we subtract 2036 from 2250, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 13:
The number 509 fits into 2140 4 times, leaving a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 151404.47544
Deduct 2036 from 2140 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 151404.47544 with a balance of 0.000104.
