We're dividing 28987457 by 993 
Let's see how many times 993 fits into 28987457.

Let's proceed to step 1:
993 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 993

Step 2:
993 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 993

Let's proceed to step 3:
When dividing 289 by 993, we get 0 with a remainder of 289.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 289, we get 289.
Fetch the next digit (8) from the dividend, attach it to 289 and continue: 2898 / 993

Going ahead to step 4:
The number 993 fits into 2898 2 times, leaving a remainder of 912.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1986 from 2898 leaves us with 912.
Grab the next digit (7) from the dividend, add it to 912, then carry on: 9127 / 993

On to step 5:
When dividing 9127 by 993, we get 9 with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 8937 from 9127 leaves us with 190.
Fetch the next digit (4) from the dividend, attach it to 190 and continue: 1904 / 993

Step 6:
The number 993 fits into 1904 1 times, leaving a remainder of 911.
Use 1 as the next digit of our solution. 
Result so far: 291.0
The remainder is 911 after subtracting 993 from 1904.
Fetch the next digit (5) from the dividend, attach it to 911 and continue: 9115 / 993

Let's proceed to step 7:
993 goes into 9115 9 times with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 2919.0
Subtracting 8937 from 9115 leaves us with 178.
Fetch the next digit (7) from the dividend, attach it to 178 and continue: 1787 / 993

Going ahead to step 8:
If we divide 1787 by 993, we get 1 and a remainder of 794.
Write down 1 as next digit of the result. 
Result so far: 29191.0
Deduct 993 from 1787 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

On to step 9:
993 goes into 7940 7 times with a remainder of 989.
Record the quotient 7 as the next digit in the result. 
Result so far: 29191.7
The remainder is 989 after subtracting 6951 from 7940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9890, and continue the process.

Step 10:
The number 993 fits into 9890 9 times, leaving a remainder of 953.
The next digit of our result is 9. 
Result so far: 29191.79
If we take 8937 away from 9890, we end up with 953.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9530, and continue the process.

Advancing to step 11:
993 goes into 9530 9 times with a remainder of 593.
The number 9 becomes the next digit in our result. 
Result so far: 29191.799
Subtracting 8937 from 9530 leaves us with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

The final outcome is 29191.799, with a leftover of 0.0593.
