99780049 ÷ 993 
Our goal is to divide 99780049 by 993.

Moving on to step 1:
If we divide 9 by 993, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 993

Let's proceed to step 2:
When dividing 99 by 993, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 993

Moving on to step 3:
993 can be fit into 997 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 993 away from 997, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 993

Step 4:
The number 993 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 48 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 993

On to step 5:
The number 993 fits into 480 0 times, leaving a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 100.0
If we subtract 0 from 480, we get 480.
Bring next digit (0) of the dividend behind the 480 and repeat the process: 4800 / 993

Advancing to step 6:
993 goes into 4800 4 times with a remainder of 828.
Write down 4 as next digit of the result. 
Result so far: 1004.0
Subtracting 3972 from 4800 leaves us with 828.
Fetch the next digit (4) from the dividend, attach it to 828 and continue: 8284 / 993

Going ahead to step 7:
When dividing 8284 by 993, we get 8 with a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 10048.0
Deduct 7944 from 8284 and we're left with 340.
Fetch the next digit (9) from the dividend, attach it to 340 and continue: 3409 / 993

Going ahead to step 8:
The number 993 fits into 3409 3 times, leaving a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 100483.0
If we take 2979 away from 3409, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
If we divide 4300 by 993, we get 4 and a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 100483.4
Subtracting 3972 from 4300 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 10:
3280 divided by 993 is 3 with a remainder of 301.
Write down 3 as next digit of the result. 
Result so far: 100483.43
Deduct 2979 from 3280 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 11:
The number 993 fits into 3010 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 100483.433
Deduct 2979 from 3010 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 100483.433 with a remainder of 0.0031.
