We divide 609355 by 77
We want to divide 609355 by 77.

Advancing to step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 77

Moving on to step 2:
60 divided by 77 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 77

Going ahead to step 3:
77 can be fit into 609 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 70 after subtracting 539 from 609.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 77

On to step 4:
When dividing 703 by 77, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 693 from 703 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 77

Step 5:
The number 77 fits into 105 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 791.0
If we take 77 away from 105, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 77

Let's proceed to step 6:
285 divided by 77 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 7913.0
Deduct 231 from 285 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
When dividing 540 by 77, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7913.7
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 77, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7913.7
Subtract 0 from 10 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.

Let's proceed to step 9:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 7913.701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 7913.7012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
760 divided by 77 is 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 7913.70129
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
670 divided by 77 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 7913.701298
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7913.7012987
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
When dividing 10 by 77, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7913.7012987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 7913.7012987 and a remainder of 1e-08.
