80412817 ÷ 769 
Our goal is to divide 80412817 by 769.

Moving on to step 1:
The number 769 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 769

On to step 2:
769 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 769

On to step 3:
The number 769 fits into 804 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 769 from 804 to get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 769

On to step 4:
When dividing 351 by 769, we get 0 with a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 351 and we're left with 351.
Grab the next digit (2) from the dividend, add it to 351, then carry on: 3512 / 769

Moving on to step 5:
769 goes into 3512 4 times with a remainder of 436.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 436 after subtracting 3076 from 3512.
Grab the next digit (8) from the dividend, add it to 436, then carry on: 4368 / 769

On to step 6:
4368 divided by 769 is 5 with a remainder of 523.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
If we subtract 3845 from 4368, we get 523.
Fetch the next digit (1) from the dividend, attach it to 523 and continue: 5231 / 769

Going ahead to step 7:
When dividing 5231 by 769, we get 6 with a remainder of 617.
Use 6 as the next digit of our solution. 
Result so far: 10456.0
If we subtract 4614 from 5231, we get 617.
Bring next digit (7) of the dividend behind the 617 and repeat the process: 6177 / 769

Let's proceed to step 8:
769 goes into 6177 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 104568.0
Deduct 6152 from 6177 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 769 fits into 250 0 times, leaving a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 104568.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
If we divide 2500 by 769, we get 3 and a remainder of 193.
The next digit of our result is 3. 
Result so far: 104568.03
If we take 2307 away from 2500, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 11:
If we divide 1930 by 769, we get 2 and a remainder of 392.
The number 2 becomes the next digit in our result. 
Result so far: 104568.032
If we take 1538 away from 1930, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 12:
769 goes into 3920 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 104568.0325
Subtract 3845 from 3920 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
769 can be fit into 750 0 times, resulting in a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 104568.0325
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
The number 769 fits into 7500 9 times, leaving a remainder of 579.
Put 9 as the next digit of the answer. 
Result so far: 104568.032509
Subtract 6921 from 7500 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 15:
The number 769 fits into 5790 7 times, leaving a remainder of 407.
Put 7 as the next digit of the answer. 
Result so far: 104568.0325097
The remainder is 407 after subtracting 5383 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 16:
4070 divided by 769 is 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 104568.03250975
If we take 3845 away from 4070, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 104568.03250975, and the remainder is 2.25e-07.
