We're dividing 66480964 by 998 
We want to divide 66480964 by 998.

Advancing to step 1:
The number 998 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 998

Moving on to step 2:
66 divided by 998 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 998

On to step 3:
998 goes into 664 0 times with a remainder of 664.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 664 and we're left with 664.
Include the next digit (8) from the dividend after 664, then repeat: 6648 / 998

Advancing to step 4:
When dividing 6648 by 998, we get 6 with a remainder of 660.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5988 from 6648 leaves us with 660.
Grab the next digit (0) from the dividend, add it to 660, then carry on: 6600 / 998

Advancing to step 5:
998 can be fit into 6600 6 times, resulting in a remainder of 612.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 5988 from 6600 and we're left with 612.
Take the next digit (9) from the dividend and append it to 612, then repeat: 6129 / 998

Step 6:
If we divide 6129 by 998, we get 6 and a remainder of 141.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
If we take 5988 away from 6129, we end up with 141.
Bring next digit (6) of the dividend behind the 141 and repeat the process: 1416 / 998

On to step 7:
1416 divided by 998 is 1 with a remainder of 418.
Put 1 as the next digit of the answer. 
Result so far: 6661.0
If we take 998 away from 1416, we end up with 418.
Take the next digit (4) from the dividend and append it to 418, then repeat: 4184 / 998

Moving on to step 8:
If we divide 4184 by 998, we get 4 and a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 66614.0
Subtracting 3992 from 4184 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
1920 divided by 998 is 1 with a remainder of 922.
The number 1 becomes the next digit in our result. 
Result so far: 66614.1
If we take 998 away from 1920, we end up with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Step 10:
If we divide 9220 by 998, we get 9 and a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 66614.19
Subtract 8982 from 9220 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 11:
998 can be fit into 2380 2 times, resulting in a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 66614.192
If we take 1996 away from 2380, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 12:
3840 divided by 998 is 3 with a remainder of 846.
Record the quotient 3 as the next digit in the result. 
Result so far: 66614.1923
Subtract 2994 from 3840 to get 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Moving on to step 13:
998 goes into 8460 8 times with a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 66614.19238
Subtracting 7984 from 8460 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 14:
4760 divided by 998 is 4 with a remainder of 768.
Use 4 as the next digit of our solution. 
Result so far: 66614.192384
Subtract 3992 from 4760 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 15:
The number 998 fits into 7680 7 times, leaving a remainder of 694.
Record the quotient 7 as the next digit in the result. 
Result so far: 66614.1923847
If we take 6986 away from 7680, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 16:
When dividing 6940 by 998, we get 6 with a remainder of 952.
Write down 6 as next digit of the result. 
Result so far: 66614.19238476
Subtract 5988 from 6940 to get 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

After the division, we end up with 66614.19238476 and a remainder of 9.52e-07.
