55408193 divided by 993 
We're looking to find how many times 993 goes into 55408193.

Let's proceed to step 1:
The number 993 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 993

Going ahead to step 2:
993 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 993

Step 3:
554 divided by 993 is 0 with a remainder of 554.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 554 leaves us with 554.
Fetch the next digit (0) from the dividend, attach it to 554 and continue: 5540 / 993

Moving on to step 4:
When dividing 5540 by 993, we get 5 with a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4965 away from 5540, we end up with 575.
Bring next digit (8) of the dividend behind the 575 and repeat the process: 5758 / 993

Going ahead to step 5:
993 can be fit into 5758 5 times, resulting in a remainder of 793.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 793 after subtracting 4965 from 5758.
Append the next digit (1) from the dividend to 793 and continue with: 7931 / 993

Advancing to step 6:
If we divide 7931 by 993, we get 7 and a remainder of 980.
Record the quotient 7 as the next digit in the result. 
Result so far: 557.0
Deduct 6951 from 7931 and we're left with 980.
Append the next digit (9) from the dividend to 980 and continue with: 9809 / 993

On to step 7:
If we divide 9809 by 993, we get 9 and a remainder of 872.
Record the quotient 9 as the next digit in the result. 
Result so far: 5579.0
Deduct 8937 from 9809 and we're left with 872.
Include the next digit (3) from the dividend after 872, then repeat: 8723 / 993

Moving on to step 8:
993 goes into 8723 8 times with a remainder of 779.
Put 8 as the next digit of the answer. 
Result so far: 55798.0
If we take 7944 away from 8723, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 9:
If we divide 7790 by 993, we get 7 and a remainder of 839.
The number 7 becomes the next digit in our result. 
Result so far: 55798.7
The remainder is 839 after subtracting 6951 from 7790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Moving on to step 10:
If we divide 8390 by 993, we get 8 and a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 55798.78
The remainder is 446 after subtracting 7944 from 8390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 11:
993 can be fit into 4460 4 times, resulting in a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 55798.784
Deduct 3972 from 4460 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
993 can be fit into 4880 4 times, resulting in a remainder of 908.
Put 4 as the next digit of the answer. 
Result so far: 55798.7844
Subtract 3972 from 4880 to get 908.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

The final outcome is 55798.7844, with a leftover of 0.00908.
