665668 ÷ 99 
We want to figure out the number of times 665668 can be divided by 99.

Going ahead to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 99

Going ahead to step 2:
If we divide 66 by 99, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 99

On to step 3:
99 can be fit into 665 6 times, resulting in a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 594 from 665 and we're left with 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 99

Going ahead to step 4:
When dividing 716 by 99, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 693 from 716 and we're left with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 99

Advancing to step 5:
236 divided by 99 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 672.0
Deduct 198 from 236 and we're left with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 99

Step 6:
99 goes into 388 3 times with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 6723.0
Subtracting 297 from 388 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 7:
99 can be fit into 910 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 6723.9
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
99 can be fit into 190 1 times, resulting in a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 6723.91
If we subtract 99 from 190, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 9:
If we divide 910 by 99, we get 9 and a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 6723.919
The remainder is 19 after subtracting 891 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
190 divided by 99 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 6723.9191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 11:
When dividing 910 by 99, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 6723.91919
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
When dividing 190 by 99, we get 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6723.919191
Subtract 99 from 190 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 13:
If we divide 910 by 99, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 6723.9191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 6723.91919191
Subtracting 99 from 190 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The quotient of the division is 6723.91919191, and the remainder is 9.1e-08.
