We look at the division of 800730 by 77 
Let's see how many times 77 fits into 800730.

Going ahead to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 77

Advancing to step 2:
77 goes into 80 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 77 from 80, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 77

Advancing to step 3:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 77

Moving on to step 4:
77 goes into 307 3 times with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we take 231 away from 307, we end up with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 77

On to step 5:
77 goes into 763 9 times with a remainder of 70.
The next digit of our result is 9. 
Result so far: 1039.0
Subtracting 693 from 763 leaves us with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 77

Let's proceed to step 6:
If we divide 700 by 77, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 10399.0
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10399.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
The number 77 fits into 700 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 10399.09
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 77 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10399.09
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
The number 77 fits into 700 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 10399.0909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10399.0909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
700 divided by 77 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 10399.090909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
When dividing 70 by 77, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10399.090909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
77 goes into 700 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 10399.09090909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 10399.09090909, and the remainder is 7e-09.
