68636868 ÷ 990 
Our goal is to divide 68636868 by 990.

Moving on to step 1:
990 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 990

Going ahead to step 2:
When dividing 68 by 990, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 990

Step 3:
If we divide 686 by 990, we get 0 and a remainder of 686.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 686, we end up with 686.
Grab the next digit (3) from the dividend, add it to 686, then carry on: 6863 / 990

Step 4:
If we divide 6863 by 990, we get 6 and a remainder of 923.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 923 after subtracting 5940 from 6863.
Take the next digit (6) from the dividend and append it to 923, then repeat: 9236 / 990

Step 5:
If we divide 9236 by 990, we get 9 and a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 8910 from 9236 and we're left with 326.
Take the next digit (8) from the dividend and append it to 326, then repeat: 3268 / 990

On to step 6:
3268 divided by 990 is 3 with a remainder of 298.
Record the quotient 3 as the next digit in the result. 
Result so far: 693.0
Deduct 2970 from 3268 and we're left with 298.
Include the next digit (6) from the dividend after 298, then repeat: 2986 / 990

Step 7:
990 can be fit into 2986 3 times, resulting in a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 6933.0
If we take 2970 away from 2986, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 990

On to step 8:
990 can be fit into 168 0 times, resulting in a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 69330.0
Deduct 0 from 168 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
The number 990 fits into 1680 1 times, leaving a remainder of 690.
Use 1 as the next digit of our solution. 
Result so far: 69330.1
Subtract 990 from 1680 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 10:
When dividing 6900 by 990, we get 6 with a remainder of 960.
Record the quotient 6 as the next digit in the result. 
Result so far: 69330.16
If we subtract 5940 from 6900, we get 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Going ahead to step 11:
If we divide 9600 by 990, we get 9 and a remainder of 690.
Put 9 as the next digit of the answer. 
Result so far: 69330.169
If we subtract 8910 from 9600, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 12:
990 goes into 6900 6 times with a remainder of 960.
Record the quotient 6 as the next digit in the result. 
Result so far: 69330.1696
If we take 5940 away from 6900, we end up with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Advancing to step 13:
990 goes into 9600 9 times with a remainder of 690.
Use 9 as the next digit of our solution. 
Result so far: 69330.16969
Subtract 8910 from 9600 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 14:
When dividing 6900 by 990, we get 6 with a remainder of 960.
Write down 6 as next digit of the result. 
Result so far: 69330.169696
Deduct 5940 from 6900 and we're left with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Moving on to step 15:
990 can be fit into 9600 9 times, resulting in a remainder of 690.
Use 9 as the next digit of our solution. 
Result so far: 69330.1696969
Subtracting 8910 from 9600 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 16:
When dividing 6900 by 990, we get 6 with a remainder of 960.
Record the quotient 6 as the next digit in the result. 
Result so far: 69330.16969696
Subtracting 5940 from 6900 leaves us with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Our division results in 69330.16969696 with a remaining 9.6e-07.
