We look at the division of 28709946 by 993 
We want to figure out the number of times 28709946 can be divided by 993.

Step 1:
2 divided by 993 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 993

Let's proceed to step 2:
The number 993 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 993

On to step 3:
The number 993 fits into 287 0 times, leaving a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 287 after subtracting 0 from 287.
Take the next digit (0) from the dividend and append it to 287, then repeat: 2870 / 993

Going ahead to step 4:
2870 divided by 993 is 2 with a remainder of 884.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1986 away from 2870, we end up with 884.
Include the next digit (9) from the dividend after 884, then repeat: 8849 / 993

Going ahead to step 5:
When dividing 8849 by 993, we get 8 with a remainder of 905.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 7944 from 8849 to get 905.
Grab the next digit (9) from the dividend, add it to 905, then carry on: 9059 / 993

Let's proceed to step 6:
The number 993 fits into 9059 9 times, leaving a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 289.0
If we take 8937 away from 9059, we end up with 122.
Grab the next digit (4) from the dividend, add it to 122, then carry on: 1224 / 993

Step 7:
993 can be fit into 1224 1 times, resulting in a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 2891.0
Subtract 993 from 1224 to get 231.
Grab the next digit (6) from the dividend, add it to 231, then carry on: 2316 / 993

Moving on to step 8:
993 can be fit into 2316 2 times, resulting in a remainder of 330.
Use 2 as the next digit of our solution. 
Result so far: 28912.0
If we take 1986 away from 2316, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 9:
993 can be fit into 3300 3 times, resulting in a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 28912.3
Subtracting 2979 from 3300 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 10:
993 can be fit into 3210 3 times, resulting in a remainder of 231.
Use 3 as the next digit of our solution. 
Result so far: 28912.33
If we take 2979 away from 3210, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final result is 28912.33 with a remainder of 0.231.
