66404563 divided by 994 
We're looking to find how many times 994 goes into 66404563.

Step 1:
994 can be fit into 6 0 times, resulting in 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 994

On to step 2:
66 divided by 994 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 994

Step 3:
664 divided by 994 is 0 with a remainder of 664.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Append the next digit (0) from the dividend to 664 and continue with: 6640 / 994

Moving on to step 4:
If we divide 6640 by 994, we get 6 and a remainder of 676.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5964 from 6640 to get 676.
Fetch the next digit (4) from the dividend, attach it to 676 and continue: 6764 / 994

Step 5:
When dividing 6764 by 994, we get 6 with a remainder of 800.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 800 after subtracting 5964 from 6764.
Append the next digit (5) from the dividend to 800 and continue with: 8005 / 994

Advancing to step 6:
994 can be fit into 8005 8 times, resulting in a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
The remainder is 53 after subtracting 7952 from 8005.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 994

On to step 7:
536 divided by 994 is 0 with a remainder of 536.
The number 0 becomes the next digit in our result. 
Result so far: 6680.0
The remainder is 536 after subtracting 0 from 536.
Grab the next digit (3) from the dividend, add it to 536, then carry on: 5363 / 994

Step 8:
5363 divided by 994 is 5 with a remainder of 393.
Record the quotient 5 as the next digit in the result. 
Result so far: 66805.0
If we take 4970 away from 5363, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 9:
994 goes into 3930 3 times with a remainder of 948.
The next digit of our result is 3. 
Result so far: 66805.3
Subtracting 2982 from 3930 leaves us with 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

On to step 10:
994 goes into 9480 9 times with a remainder of 534.
Put 9 as the next digit of the answer. 
Result so far: 66805.39
If we subtract 8946 from 9480, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 11:
5340 divided by 994 is 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 66805.395
The remainder is 370 after subtracting 4970 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
3700 divided by 994 is 3 with a remainder of 718.
Write down 3 as next digit of the result. 
Result so far: 66805.3953
If we take 2982 away from 3700, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 13:
When dividing 7180 by 994, we get 7 with a remainder of 222.
The number 7 becomes the next digit in our result. 
Result so far: 66805.39537
If we subtract 6958 from 7180, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 14:
994 goes into 2220 2 times with a remainder of 232.
Put 2 as the next digit of the answer. 
Result so far: 66805.395372
If we subtract 1988 from 2220, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 15:
2320 divided by 994 is 2 with a remainder of 332.
The next digit of our result is 2. 
Result so far: 66805.3953722
The remainder is 332 after subtracting 1988 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 66805.3953722, with a leftover of 3.32e-06.
