646333 divided by 77 
We want to figure out the number of times 646333 can be divided by 77.

Step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 77

Let's proceed to step 2:
When dividing 64 by 77, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 77

Let's proceed to step 3:
77 can be fit into 646 8 times, resulting in a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 616 from 646 to get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 77

Step 4:
77 goes into 303 3 times with a remainder of 72.
The next digit of our result is 3. 
Result so far: 83.0
The remainder is 72 after subtracting 231 from 303.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 77

Advancing to step 5:
77 goes into 723 9 times with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 839.0
Subtract 693 from 723 to get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 77

Going ahead to step 6:
When dividing 303 by 77, we get 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 8393.0
If we subtract 231 from 303, we 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.

Going ahead to step 7:
If we divide 720 by 77, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 8393.9
If we subtract 693 from 720, we get 27.
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 8:
270 divided by 77 is 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 8393.93
Deduct 231 from 270 and we're left 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.

On to step 9:
77 can be fit into 390 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8393.935
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 10:
If we divide 50 by 77, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8393.935
The remainder is 50 after subtracting 0 from 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 11:
When dividing 500 by 77, we get 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 8393.93506
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
77 can be fit into 380 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 8393.935064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
When dividing 720 by 77, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 8393.9350649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
The number 77 fits into 270 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 8393.93506493
If we take 231 away from 270, we end up 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.

In conclusion, the division gives 8393.93506493 with a balance of 3.9e-08.
