66084220 ÷ 998 
We want to figure out the number of times 66084220 can be divided by 998.

On to step 1:
When dividing 6 by 998, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 998

Going ahead to step 2:
When dividing 66 by 998, we get 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.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 998

Going ahead to step 3:
If we divide 660 by 998, we get 0 and a remainder of 660.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 660 leaves us with 660.
Take the next digit (8) from the dividend and append it to 660, then repeat: 6608 / 998

Moving on to step 4:
If we divide 6608 by 998, we get 6 and a remainder of 620.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 5988 from 6608, we get 620.
Append the next digit (4) from the dividend to 620 and continue with: 6204 / 998

Advancing to step 5:
998 goes into 6204 6 times with a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 5988 from 6204, we get 216.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 998

Let's proceed to step 6:
998 can be fit into 2162 2 times, resulting in a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
If we subtract 1996 from 2162, we get 166.
Grab the next digit (2) from the dividend, add it to 166, then carry on: 1662 / 998

Step 7:
998 goes into 1662 1 times with a remainder of 664.
Use 1 as the next digit of our solution. 
Result so far: 6621.0
The remainder is 664 after subtracting 998 from 1662.
Take the next digit (0) from the dividend and append it to 664, then repeat: 6640 / 998

Moving on to step 8:
998 goes into 6640 6 times with a remainder of 652.
Put 6 as the next digit of the answer. 
Result so far: 66216.0
If we subtract 5988 from 6640, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 9:
6520 divided by 998 is 6 with a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 66216.6
Subtract 5988 from 6520 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 10:
998 can be fit into 5320 5 times, resulting in a remainder of 330.
The next digit of our result is 5. 
Result so far: 66216.65
Subtract 4990 from 5320 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 11:
998 can be fit into 3300 3 times, resulting in a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 66216.653
The remainder is 306 after subtracting 2994 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 12:
The number 998 fits into 3060 3 times, leaving a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 66216.6533
If we take 2994 away from 3060, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 66216.6533 with a remaining 0.00066.
