Let's divide 664395 by 77
We want to figure out the number of times 664395 can be divided by 77.

Let's proceed to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 77

Step 2:
If we divide 66 by 77, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 77

Advancing to step 3:
77 goes into 664 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 616 away from 664, we end up with 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 77

Advancing to step 4:
77 goes into 483 6 times with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 462 from 483, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 77

Let's proceed to step 5:
The number 77 fits into 219 2 times, leaving a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 862.0
Subtracting 154 from 219 leaves us with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 77

Step 6:
77 can be fit into 655 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8628.0
The remainder is 39 after subtracting 616 from 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
If we divide 390 by 77, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8628.5
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 77, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8628.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
77 goes into 500 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 8628.506
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 77 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 8628.5064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 8628.50649
The remainder is 27 after subtracting 693 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
270 divided by 77 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 8628.506493
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
The number 77 fits into 390 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8628.5064935
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
If we divide 50 by 77, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 8628.5064935
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 8628.5064935 with a balance of 5e-08.
