798583 divided by 77 
Let's see how many times 77 fits into 798583.

On to step 1:
77 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 77

Let's proceed to step 2:
77 goes into 79 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 77 from 79.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 77

Step 3:
When dividing 28 by 77, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 77

Step 4:
285 divided by 77 is 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we subtract 231 from 285, we get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 77

Let's proceed to step 5:
77 can be fit into 548 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 1037.0
Deduct 539 from 548 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 77

On to step 6:
77 can be fit into 93 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 10371.0
Subtract 77 from 93 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 10371.2
The remainder is 6 after subtracting 154 from 160.
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 8:
77 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10371.2
If we subtract 0 from 60, we 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.

On to step 9:
600 divided by 77 is 7 with a remainder of 61.
The next digit of our result is 7. 
Result so far: 10371.207
Subtracting 539 from 600 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
If we divide 610 by 77, we get 7 and a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 10371.2077
Deduct 539 from 610 and we're left with 71.
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 10371.2077, and the remainder is 0.00071.
