12809623 ÷ 775 
We want to figure out the number of times 12809623 can be divided by 775.

Step 1:
The number 775 fits into 1 0 times, leaving 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 775

Moving on to step 2:
The number 775 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 775

Moving on to step 3:
775 can be fit into 128 0 times, resulting in a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Fetch the next digit (0) from the dividend, attach it to 128 and continue: 1280 / 775

Going ahead to step 4:
The number 775 fits into 1280 1 times, leaving a remainder of 505.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 505 after subtracting 775 from 1280.
Include the next digit (9) from the dividend after 505, then repeat: 5059 / 775

Going ahead to step 5:
775 can be fit into 5059 6 times, resulting in a remainder of 409.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 409 after subtracting 4650 from 5059.
Append the next digit (6) from the dividend to 409 and continue with: 4096 / 775

Advancing to step 6:
When dividing 4096 by 775, we get 5 with a remainder of 221.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we take 3875 away from 4096, we end up with 221.
Append the next digit (2) from the dividend to 221 and continue with: 2212 / 775

Moving on to step 7:
775 goes into 2212 2 times with a remainder of 662.
Record the quotient 2 as the next digit in the result. 
Result so far: 1652.0
If we subtract 1550 from 2212, we get 662.
Take the next digit (3) from the dividend and append it to 662, then repeat: 6623 / 775

On to step 8:
The number 775 fits into 6623 8 times, leaving a remainder of 423.
Record the quotient 8 as the next digit in the result. 
Result so far: 16528.0
The remainder is 423 after subtracting 6200 from 6623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 9:
If we divide 4230 by 775, we get 5 and a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 16528.5
Deduct 3875 from 4230 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 10:
775 can be fit into 3550 4 times, resulting in a remainder of 450.
Put 4 as the next digit of the answer. 
Result so far: 16528.54
The remainder is 450 after subtracting 3100 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 11:
775 goes into 4500 5 times with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 16528.545
Subtracting 3875 from 4500 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 12:
If we divide 6250 by 775, we get 8 and a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 16528.5458
If we take 6200 away from 6250, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
If we divide 500 by 775, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 16528.5458
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
775 goes into 5000 6 times with a remainder of 350.
The next digit of our result is 6. 
Result so far: 16528.545806
Deduct 4650 from 5000 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 15:
The number 775 fits into 3500 4 times, leaving a remainder of 400.
Use 4 as the next digit of our solution. 
Result so far: 16528.5458064
Subtracting 3100 from 3500 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 16:
775 goes into 4000 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 16528.54580645
Deduct 3875 from 4000 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 16528.54580645 with a remaining 1.25e-07.
