99169716 ÷ 660 
Our goal is to divide 99169716 by 660.

Let's proceed to step 1:
660 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 660

Moving on to step 2:
660 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 660

Step 3:
660 can be fit into 991 1 times, resulting in a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 331 after subtracting 660 from 991.
Append the next digit (6) from the dividend to 331 and continue with: 3316 / 660

Let's proceed to step 4:
If we divide 3316 by 660, we get 5 and a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 3300 from 3316 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 660

Moving on to step 5:
When dividing 169 by 660, we get 0 with a remainder of 169.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
If we take 0 away from 169, we end up with 169.
Take the next digit (7) from the dividend and append it to 169, then repeat: 1697 / 660

Going ahead to step 6:
1697 divided by 660 is 2 with a remainder of 377.
The number 2 becomes the next digit in our result. 
Result so far: 1502.0
If we take 1320 away from 1697, we end up with 377.
Grab the next digit (1) from the dividend, add it to 377, then carry on: 3771 / 660

Step 7:
3771 divided by 660 is 5 with a remainder of 471.
The number 5 becomes the next digit in our result. 
Result so far: 15025.0
Subtracting 3300 from 3771 leaves us with 471.
Bring next digit (6) of the dividend behind the 471 and repeat the process: 4716 / 660

Going ahead to step 8:
660 goes into 4716 7 times with a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 150257.0
If we take 4620 away from 4716, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
960 divided by 660 is 1 with a remainder of 300.
The next digit of our result is 1. 
Result so far: 150257.1
Subtracting 660 from 960 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
660 goes into 3000 4 times with a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 150257.14
Subtract 2640 from 3000 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
If we divide 3600 by 660, we get 5 and a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 150257.145
Subtract 3300 from 3600 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 12:
If we divide 3000 by 660, we get 4 and a remainder of 360.
The next digit of our result is 4. 
Result so far: 150257.1454
The remainder is 360 after subtracting 2640 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
660 goes into 3600 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 150257.14545
The remainder is 300 after subtracting 3300 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
If we divide 3000 by 660, we get 4 and a remainder of 360.
The next digit of our result is 4. 
Result so far: 150257.145454
Subtract 2640 from 3000 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
3600 divided by 660 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 150257.1454545
If we subtract 3300 from 3600, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 16:
660 goes into 3000 4 times with a remainder of 360.
Write down 4 as next digit of the result. 
Result so far: 150257.14545454
If we take 2640 away from 3000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 150257.14545454 with a remaining 3.6e-07.
