We're dividing 646775 by 99 
Let's see how many times 99 fits into 646775.

Going ahead to step 1:
99 can be fit into 6 0 times, resulting in 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 99

Moving on to step 2:
99 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 99

Moving on to step 3:
99 can be fit into 646 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 594 from 646 and we're left with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 99

Step 4:
The number 99 fits into 527 5 times, leaving a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 495 from 527 to get 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 99

Advancing to step 5:
If we divide 327 by 99, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 653.0
If we subtract 297 from 327, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 99

Step 6:
When dividing 305 by 99, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 6533.0
Subtracting 297 from 305 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 99, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6533.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
If we divide 800 by 99, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6533.08
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
The number 99 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6533.08
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
The number 99 fits into 800 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 6533.0808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
80 divided by 99 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 6533.0808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
If we divide 800 by 99, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6533.080808
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 99, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6533.080808
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
When dividing 800 by 99, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6533.08080808
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 6533.08080808 with a remainder of 8e-09.
