13123603 ÷ 776 
Let's see how many times 776 fits into 13123603.

Step 1:
When dividing 1 by 776, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 776

Moving on to step 2:
776 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 776

On to step 3:
776 can be fit into 131 0 times, resulting in a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 131, we get 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 776

Moving on to step 4:
When dividing 1312 by 776, we get 1 with a remainder of 536.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 776 from 1312 to get 536.
Fetch the next digit (3) from the dividend, attach it to 536 and continue: 5363 / 776

Advancing to step 5:
5363 divided by 776 is 6 with a remainder of 707.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 4656 from 5363 leaves us with 707.
Take the next digit (6) from the dividend and append it to 707, then repeat: 7076 / 776

Advancing to step 6:
7076 divided by 776 is 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 169.0
The remainder is 92 after subtracting 6984 from 7076.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 776

Step 7:
920 divided by 776 is 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 1691.0
If we take 776 away from 920, we end up with 144.
Include the next digit (3) from the dividend after 144, then repeat: 1443 / 776

Step 8:
When dividing 1443 by 776, we get 1 with a remainder of 667.
Write down 1 as next digit of the result. 
Result so far: 16911.0
Subtracting 776 from 1443 leaves us with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Moving on to step 9:
When dividing 6670 by 776, we get 8 with a remainder of 462.
Put 8 as the next digit of the answer. 
Result so far: 16911.8
Subtract 6208 from 6670 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 10:
The number 776 fits into 4620 5 times, leaving a remainder of 740.
Put 5 as the next digit of the answer. 
Result so far: 16911.85
Subtracting 3880 from 4620 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 11:
When dividing 7400 by 776, we get 9 with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 16911.859
If we subtract 6984 from 7400, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 12:
4160 divided by 776 is 5 with a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 16911.8595
Subtracting 3880 from 4160 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
If we divide 2800 by 776, we get 3 and a remainder of 472.
Use 3 as the next digit of our solution. 
Result so far: 16911.85953
Subtracting 2328 from 2800 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 14:
776 can be fit into 4720 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 16911.859536
Subtract 4656 from 4720 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
The number 776 fits into 640 0 times, leaving a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 16911.859536
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
776 goes into 6400 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 16911.85953608
Subtracting 6208 from 6400 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 16911.85953608 with a remaining 1.92e-07.
