Let's divide 66907817 by 998
We're looking to find how many times 998 goes into 66907817.

Moving on to step 1:
998 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
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 / 998

Advancing to step 2:
66 divided by 998 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 998

Moving on to step 3:
669 divided by 998 is 0 with a remainder of 669.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 669 after subtracting 0 from 669.
Bring next digit (0) of the dividend behind the 669 and repeat the process: 6690 / 998

Advancing to step 4:
998 can be fit into 6690 6 times, resulting in a remainder of 702.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5988 from 6690 to get 702.
Include the next digit (7) from the dividend after 702, then repeat: 7027 / 998

Step 5:
998 can be fit into 7027 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 6986 from 7027 leaves us with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 998

Moving on to step 6:
The number 998 fits into 418 0 times, leaving a remainder of 418.
Record the quotient 0 as the next digit in the result. 
Result so far: 670.0
Subtracting 0 from 418 leaves us with 418.
Take the next digit (1) from the dividend and append it to 418, then repeat: 4181 / 998

Step 7:
998 goes into 4181 4 times with a remainder of 189.
Write down 4 as next digit of the result. 
Result so far: 6704.0
If we take 3992 away from 4181, we end up with 189.
Bring next digit (7) of the dividend behind the 189 and repeat the process: 1897 / 998

Step 8:
1897 divided by 998 is 1 with a remainder of 899.
The next digit of our result is 1. 
Result so far: 67041.0
Deduct 998 from 1897 and we're left with 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

Going ahead to step 9:
When dividing 8990 by 998, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 67041.9
Subtracting 8982 from 8990 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
The number 998 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 67041.9
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
The number 998 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 67041.9
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 67041.9, with a leftover of 0.08.
