664510 divided by 99 
We want to divide 664510 by 99.

On to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 99

Advancing to step 2:
If we divide 66 by 99, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 99

Let's proceed to step 3:
664 divided by 99 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 594 from 664 and we're left with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 99

Let's proceed to step 4:
99 goes into 705 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 693 from 705 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 99

Moving on to step 5:
The number 99 fits into 121 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 671.0
If we subtract 99 from 121, we get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 99

On to step 6:
99 can be fit into 220 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 6712.0
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
99 can be fit into 220 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 6712.2
If we take 198 away from 220, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 99, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 6712.22
Deduct 198 from 220 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 6712.22, and the remainder is 0.022.
