We divide 661995 by 99
We want to figure out the number of times 661995 can be divided by 99.

On to step 1:
6 divided by 99 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 99

Moving on to step 2:
99 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 99

Going ahead to step 3:
When dividing 661 by 99, we get 6 with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 594 from 661 and we're left with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 99

Let's proceed to step 4:
The number 99 fits into 679 6 times, leaving a remainder of 85.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 594 from 679 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 99

On to step 5:
859 divided by 99 is 8 with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
Deduct 792 from 859 and we're left with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 99

Step 6:
When dividing 675 by 99, we get 6 with a remainder of 81.
Record the quotient 6 as the next digit in the result. 
Result so far: 6686.0
The remainder is 81 after subtracting 594 from 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
When dividing 810 by 99, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 6686.8
Subtracting 792 from 810 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
99 can be fit into 180 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 6686.81
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
If we divide 810 by 99, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 6686.818
Subtracting 792 from 810 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 99 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 6686.8181
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 11:
If we divide 810 by 99, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 6686.81818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
When dividing 180 by 99, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 6686.818181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
99 goes into 810 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 6686.8181818
Subtract 792 from 810 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
When dividing 180 by 99, we get 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 6686.81818181
The remainder is 81 after subtracting 99 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

After the division, we end up with 6686.81818181 and a remainder of 8.1e-08.
