660136 ÷ 99 
Our goal is to divide 660136 by 99.

Let's proceed to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 99

Going ahead to step 2:
If we divide 66 by 99, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 99

Going ahead to step 3:
If we divide 660 by 99, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 66 after subtracting 594 from 660.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 99

Moving on to step 4:
99 goes into 661 6 times with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 594 from 661 and we're left with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 99

Let's proceed to step 5:
When dividing 673 by 99, we get 6 with a remainder of 79.
The next digit of our result is 6. 
Result so far: 666.0
Subtract 594 from 673 to get 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 99

Going ahead to step 6:
When dividing 796 by 99, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 6668.0
Deduct 792 from 796 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 99 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6668.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 99 fits into 400 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 6668.04
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 99, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6668.04
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
99 goes into 400 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6668.0404
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 99 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6668.0404
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 99, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 6668.040404
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6668.040404
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 99, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6668.04040404
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 6668.04040404 with a remaining 4e-09.
