The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 993

Advancing to step 2:
If we divide 38 by 993, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 993

Moving on to step 3:
389 divided by 993 is 0 with a remainder of 389.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 389 after subtracting 0 from 389.

Moving on to step 4:
993 can be fit into 3895 3 times, resulting in a remainder of 916.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 916 after subtracting 2979 from 3895.
Grab the next digit (0) from the dividend, add it to 916, then carry on: 9160 / 993

On to step 5:
993 can be fit into 9160 9 times, resulting in a remainder of 223.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 8937 from 9160 and we're left with 223.
Fetch the next digit (1) from the dividend, attach it to 223 and continue: 2231 / 993

Moving on to step 6:
2231 divided by 993 is 2 with a remainder of 245.
Write down 2 as next digit of the result. 
Result so far: 392.0
If we subtract 1986 from 2231, we get 245.

On to step 7:
2456 divided by 993 is 2 with a remainder of 470.
Put 2 as the next digit of the answer. 
Result so far: 3922.0
If we subtract 1986 from 2456, we get 470.
Append the next digit (8) from the dividend to 470 and continue with: 4708 / 993

Step 8:
The number 993 fits into 4708 4 times, leaving a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 39224.0
Subtract 3972 from 4708 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 9:
The number 993 fits into 7360 7 times, leaving a remainder of 409.
Use 7 as the next digit of our solution. 
Result so far: 39224.7
The remainder is 409 after subtracting 6951 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 10:
If we divide 4090 by 993, we get 4 and a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 39224.74
Deduct 3972 from 4090 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 11:
1180 divided by 993 is 1 with a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 39224.741
Subtracting 993 from 1180 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 12:
If we divide 1870 by 993, we get 1 and a remainder of 877.
Put 1 as the next digit of the answer. 
Result so far: 39224.7411
Deduct 993 from 1870 and we're left with 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

Our division results in 39224.7411 with a remaining 0.00877.
