17718840 ÷ 993 
We want to figure out the number of times 17718840 can be divided by 993.

Let's proceed to step 1:
When dividing 1 by 993, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 993

Let's proceed to step 2:
993 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 993

Moving on to step 3:
993 can be fit into 177 0 times, resulting in a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 177 to get 177.
Take the next digit (1) from the dividend and append it to 177, then repeat: 1771 / 993

On to step 4:
1771 divided by 993 is 1 with a remainder of 778.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 993 away from 1771, we end up with 778.
Take the next digit (8) from the dividend and append it to 778, then repeat: 7788 / 993

Advancing to step 5:
If we divide 7788 by 993, we get 7 and a remainder of 837.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 6951 from 7788, we get 837.
Grab the next digit (8) from the dividend, add it to 837, then carry on: 8378 / 993

Let's proceed to step 6:
The number 993 fits into 8378 8 times, leaving a remainder of 434.
The next digit of our result is 8. 
Result so far: 178.0
Deduct 7944 from 8378 and we're left with 434.
Grab the next digit (4) from the dividend, add it to 434, then carry on: 4344 / 993

Step 7:
The number 993 fits into 4344 4 times, leaving a remainder of 372.
The next digit of our result is 4. 
Result so far: 1784.0
The remainder is 372 after subtracting 3972 from 4344.
Bring next digit (0) of the dividend behind the 372 and repeat the process: 3720 / 993

Moving on to step 8:
If we divide 3720 by 993, we get 3 and a remainder of 741.
Put 3 as the next digit of the answer. 
Result so far: 17843.0
Deduct 2979 from 3720 and we're left with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Moving on to step 9:
993 can be fit into 7410 7 times, resulting in a remainder of 459.
Use 7 as the next digit of our solution. 
Result so far: 17843.7
If we take 6951 away from 7410, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 10:
If we divide 4590 by 993, we get 4 and a remainder of 618.
Write down 4 as next digit of the result. 
Result so far: 17843.74
If we subtract 3972 from 4590, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 11:
6180 divided by 993 is 6 with a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 17843.746
The remainder is 222 after subtracting 5958 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 12:
If we divide 2220 by 993, we get 2 and a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 17843.7462
If we subtract 1986 from 2220, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 13:
If we divide 2340 by 993, we get 2 and a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 17843.74622
If we take 1986 away from 2340, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final result is 17843.74622 with a remainder of 0.000354.
