We're dividing 764209 by 80 
We want to divide 764209 by 80.

On to step 1:
7 divided by 80 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 80

Let's proceed to step 2:
76 divided by 80 is 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 80

Let's proceed to step 3:
80 can be fit into 764 9 times, resulting in a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 44 after subtracting 720 from 764.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 80

Advancing to step 4:
When dividing 442 by 80, we get 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we subtract 400 from 442, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 80

Moving on to step 5:
The number 80 fits into 420 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 955.0
Deduct 400 from 420 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 80

Going ahead to step 6:
The number 80 fits into 209 2 times, leaving a remainder of 49.
The next digit of our result is 2. 
Result so far: 9552.0
If we subtract 160 from 209, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
The number 80 fits into 490 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 9552.6
Subtract 480 from 490 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 9552.61
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9552.612
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9552.6125
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9552.6125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9552.6125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 9552.6125 and a remainder of 0.0.
