77739509 divided by 777 
We want to figure out the number of times 77739509 can be divided by 777.

Step 1:
777 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 777

Moving on to step 2:
If we divide 77 by 777, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 777

Moving on to step 3:
When dividing 777 by 777, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 777 from 777.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 777

Moving on to step 4:
When dividing 3 by 777, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 777

Moving on to step 5:
When dividing 39 by 777, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we take 0 away from 39, we end up with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 777

Moving on to step 6:
When dividing 395 by 777, we get 0 with a remainder of 395.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Deduct 0 from 395 and we're left with 395.
Grab the next digit (0) from the dividend, add it to 395, then carry on: 3950 / 777

Step 7:
777 can be fit into 3950 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 10005.0
If we subtract 3885 from 3950, we get 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 777

Step 8:
If we divide 659 by 777, we get 0 and a remainder of 659.
The number 0 becomes the next digit in our result. 
Result so far: 100050.0
Deduct 0 from 659 and we're left with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Moving on to step 9:
6590 divided by 777 is 8 with a remainder of 374.
The next digit of our result is 8. 
Result so far: 100050.8
Subtracting 6216 from 6590 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 10:
When dividing 3740 by 777, we get 4 with a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 100050.84
The remainder is 632 after subtracting 3108 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
When dividing 6320 by 777, we get 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 100050.848
Subtracting 6216 from 6320 leaves us 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.

Moving on to step 12:
When dividing 1040 by 777, we get 1 with a remainder of 263.
Record the quotient 1 as the next digit in the result. 
Result so far: 100050.8481
Subtracting 777 from 1040 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 13:
The number 777 fits into 2630 3 times, leaving a remainder of 299.
Put 3 as the next digit of the answer. 
Result so far: 100050.84813
Subtract 2331 from 2630 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 14:
2990 divided by 777 is 3 with a remainder of 659.
Put 3 as the next digit of the answer. 
Result so far: 100050.848133
The remainder is 659 after subtracting 2331 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

The final result is 100050.848133 with a remainder of 6.59e-05.
