We look at the division of 77404252 by 993 
We're looking to find how many times 993 goes into 77404252.

Moving on to step 1:
If we divide 7 by 993, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 993

Let's proceed to step 2:
If we divide 77 by 993, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 993

On to step 3:
993 goes into 774 0 times with a remainder of 774.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 774 to get 774.
Bring next digit (0) of the dividend behind the 774 and repeat the process: 7740 / 993

Advancing to step 4:
The number 993 fits into 7740 7 times, leaving a remainder of 789.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6951 away from 7740, we end up with 789.
Include the next digit (4) from the dividend after 789, then repeat: 7894 / 993

Going ahead to step 5:
7894 divided by 993 is 7 with a remainder of 943.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 6951 from 7894, we get 943.
Append the next digit (2) from the dividend to 943 and continue with: 9432 / 993

Going ahead to step 6:
If we divide 9432 by 993, we get 9 and a remainder of 495.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
Deduct 8937 from 9432 and we're left with 495.
Include the next digit (5) from the dividend after 495, then repeat: 4955 / 993

Step 7:
If we divide 4955 by 993, we get 4 and a remainder of 983.
The next digit of our result is 4. 
Result so far: 7794.0
Subtracting 3972 from 4955 leaves us with 983.
Append the next digit (2) from the dividend to 983 and continue with: 9832 / 993

Going ahead to step 8:
993 goes into 9832 9 times with a remainder of 895.
The next digit of our result is 9. 
Result so far: 77949.0
Subtract 8937 from 9832 to get 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

On to step 9:
The number 993 fits into 8950 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 77949.9
The remainder is 13 after subtracting 8937 from 8950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
If we divide 130 by 993, we get 0 and a remainder of 130.
The next digit of our result is 0. 
Result so far: 77949.9
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
If we divide 1300 by 993, we get 1 and a remainder of 307.
The next digit of our result is 1. 
Result so far: 77949.901
The remainder is 307 after subtracting 993 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 12:
3070 divided by 993 is 3 with a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 77949.9013
Deduct 2979 from 3070 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 13:
993 goes into 910 0 times with a remainder of 910.
Put 0 as the next digit of the answer. 
Result so far: 77949.9013
Subtract 0 from 910 to get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Let's proceed to step 14:
The number 993 fits into 9100 9 times, leaving a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 77949.901309
If we subtract 8937 from 9100, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 15:
993 goes into 1630 1 times with a remainder of 637.
Put 1 as the next digit of the answer. 
Result so far: 77949.9013091
Subtract 993 from 1630 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 16:
The number 993 fits into 6370 6 times, leaving a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 77949.90130916
Deduct 5958 from 6370 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Our division results in 77949.90130916 with a remaining 4.12e-07.
