Let's divide 815128 by 77
Let's see how many times 77 fits into 815128.

Advancing to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 77

Advancing to step 2:
When dividing 81 by 77, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 81 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 77

Moving on to step 3:
77 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 77

Step 4:
The number 77 fits into 451 5 times, leaving a remainder of 66.
The next digit of our result is 5. 
Result so far: 105.0
Subtract 385 from 451 to get 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 77

Step 5:
77 can be fit into 662 8 times, resulting in a remainder of 46.
The next digit of our result is 8. 
Result so far: 1058.0
Subtracting 616 from 662 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 77

Moving on to step 6:
468 divided by 77 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 10586.0
If we subtract 462 from 468, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 77, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 10586.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 10586.07
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
610 divided by 77 is 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 10586.077
The remainder is 71 after subtracting 539 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 10586.077, and the remainder is 0.0071.
