We're dividing 21355414 by 993 
Our goal is to divide 21355414 by 993.

Advancing to step 1:
If we divide 2 by 993, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 993

Advancing to step 2:
When dividing 21 by 993, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 993

Let's proceed to step 3:
When dividing 213 by 993, we get 0 with a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Include the next digit (5) from the dividend after 213, then repeat: 2135 / 993

Step 4:
When dividing 2135 by 993, we get 2 with a remainder of 149.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1986 from 2135 and we're left with 149.
Append the next digit (5) from the dividend to 149 and continue with: 1495 / 993

Moving on to step 5:
1495 divided by 993 is 1 with a remainder of 502.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 993 from 1495, we get 502.
Fetch the next digit (4) from the dividend, attach it to 502 and continue: 5024 / 993

Let's proceed to step 6:
If we divide 5024 by 993, we get 5 and a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtract 4965 from 5024 to get 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 993

Step 7:
993 goes into 591 0 times with a remainder of 591.
Put 0 as the next digit of the answer. 
Result so far: 2150.0
Subtracting 0 from 591 leaves us with 591.
Take the next digit (4) from the dividend and append it to 591, then repeat: 5914 / 993

Advancing to step 8:
When dividing 5914 by 993, we get 5 with a remainder of 949.
The number 5 becomes the next digit in our result. 
Result so far: 21505.0
If we subtract 4965 from 5914, we get 949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Advancing to step 9:
When dividing 9490 by 993, we get 9 with a remainder of 553.
Use 9 as the next digit of our solution. 
Result so far: 21505.9
Deduct 8937 from 9490 and we're left with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 10:
If we divide 5530 by 993, we get 5 and a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 21505.95
The remainder is 565 after subtracting 4965 from 5530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 11:
993 goes into 5650 5 times with a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 21505.955
The remainder is 685 after subtracting 4965 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

The final outcome is 21505.955, with a leftover of 0.0685.
