We're dividing 13129698 by 777 
We're looking to find how many times 777 goes into 13129698.

Advancing to step 1:
777 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 777

Step 2:
13 divided by 777 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 777

Advancing to step 3:
777 goes into 131 0 times with a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 777

Going ahead to step 4:
777 goes into 1312 1 times with a remainder of 535.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 535 after subtracting 777 from 1312.
Take the next digit (9) from the dividend and append it to 535, then repeat: 5359 / 777

Let's proceed to step 5:
The number 777 fits into 5359 6 times, leaving a remainder of 697.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 4662 from 5359 and we're left with 697.
Fetch the next digit (6) from the dividend, attach it to 697 and continue: 6976 / 777

Advancing to step 6:
6976 divided by 777 is 8 with a remainder of 760.
The next digit of our result is 8. 
Result so far: 168.0
Deduct 6216 from 6976 and we're left with 760.
Fetch the next digit (9) from the dividend, attach it to 760 and continue: 7609 / 777

Let's proceed to step 7:
777 can be fit into 7609 9 times, resulting in a remainder of 616.
The number 9 becomes the next digit in our result. 
Result so far: 1689.0
Subtract 6993 from 7609 to get 616.
Grab the next digit (8) from the dividend, add it to 616, then carry on: 6168 / 777

Step 8:
If we divide 6168 by 777, we get 7 and a remainder of 729.
The number 7 becomes the next digit in our result. 
Result so far: 16897.0
Deduct 5439 from 6168 and we're left with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Moving on to step 9:
The number 777 fits into 7290 9 times, leaving a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 16897.9
If we subtract 6993 from 7290, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 10:
If we divide 2970 by 777, we get 3 and a remainder of 639.
The number 3 becomes the next digit in our result. 
Result so far: 16897.93
If we take 2331 away from 2970, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

On to step 11:
When dividing 6390 by 777, we get 8 with a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 16897.938
The remainder is 174 after subtracting 6216 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 12:
777 can be fit into 1740 2 times, resulting in a remainder of 186.
The next digit of our result is 2. 
Result so far: 16897.9382
If we subtract 1554 from 1740, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 13:
The number 777 fits into 1860 2 times, leaving a remainder of 306.
Put 2 as the next digit of the answer. 
Result so far: 16897.93822
Deduct 1554 from 1860 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Our division results in 16897.93822 with a remaining 0.000306.
